Python attributeerror module datetime has no attribute now

Using Python datetime

Here is the simplest possible example of Python datetime usage:

from datetime import datetime dt = datetime.now() print(dt) 

It will output something like:

Common incorrect usage

There is one common mistake that is done with datetime. Here is an example of such error code:

import datetime dt = datetime.now() print(dt) 

If you run this code it will give an error:

AttributeError: module 'datetime' has no attribute 'now' 

There are two way you can fix this error. The most usual way to fix it is to write «from datetime import datetime» instead of «import datetime», here is the fixed example:

from datetime import datetime dt = datetime.now() print(dt) 

Or you can use «import datetime», but then you need to change the assignment statement:

import datetime dt = datetime.datetime.now() print(dt) 

This is because there are several things in Python datetime module:

• datetime.date
• datetime.time
• datetime.datetime
• datetime.timedelta
• datetime.tzinfo
• datetime.timezone

The module «datetime» is called after the most common class it this module, and that class is also called «datetime».

timestamp() method

To get number of seconds from «1970-01-01T00:00:00Z» you need to use datetime timestamp() method. Here is an example:

from datetime import datetime dt = datetime.now() print(type(dt.timestamp())) print(dt.timestamp()) print(dt) 

This code will output something like:

 1576582006.392294 2019-12-17 11:26:46.392294 

Create datetime object from string

Here is an example how to create datetime object from string:

from datetime import datetime str = '2019-10-12T11:12:34.000Z' dt = datetime.strptime(str, '%Y-%m-%dT%H:%M:%S.%fZ') print(type(dt)) print(dt) 

Create string from datetime object

And this is a code sample that shows how to convert datetime object to string:

from datetime import datetime dt = datetime.now() print(dt.strftime("%Y-%m-%d"))

Attributeerror module datetime has no attribute now [Solved]

In this article, we will provide solutions for attributeerror module datetime has no attribute now an error.

Asides from it we will give some example codes where in it fixes the error.

What is attributeerror module datetime has no attribute now

The attributeerror module datetime has no attribute now is an error that occurs when we call the method now straight to the datetime module.

Here is an example of how this error occurs:

import datetime print(datetime.now()) 

The code explains that when we call now method directly to the datetime module it will raise an attributeerror.

AttributeError: module ‘datetime’ has no attribute ‘now’

How to fix attributeerror module datetime has no attribute now

Here are the following solutions you can try to fix attributeerror module datetime has no attribute now

Call the now method on the datetime class

One way to fix the error is calling the now method to datetime class instead.

Here is an example code of how it works:

import datetime print(datetime.datetime.now())

2023-03-20 15:46:10.813464

Keep in mind that the local module should not be named datetime.py, otherwise it will shadow the official datetime module.

Imported the datetime class from the datetime module

Another way is to import the datetime class from the datetime module in order to avoid datetime.datetime wherein it could be confusing.

from datetime import datetime print(datetime.now())

2023-03-20 15:46:10.813464

Use an alias in import statement

Since importing datetime class from datetime is confusing, alternatively, we will use the alias to import.

So in our example we will use alias dt for datetime class, then we will call now method with dt.now() instead of datetime.now().

from datetime import datetime as dt print(dt.now())

2023-03-20 16:01:15.373088

Call the dir() function passing the imported module

Another way to debug is to call the dir() function passing it to the imported module.

import datetime """ [ 'MAXYEAR', 'MINYEAR', '__all__', '__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__spec__', 'date', 'datetime', 'datetime_CAPI', 'sys', 'time', 'timedelta', 'timezone', 'tzinfo' ] """ print(dir(datetime)) 

Once the datetime class is imported from the datetime module and pass it to the dir() function, you will see the now method in the list of attributes.

from datetime import datetime print(dir(datetime)) 

['__add__', '__class__', '__delattr__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__ne__', '__new__', '__radd__', '__reduce__', '__reduce_ex__', '__repr__', '__rsub__', '__setattr__', '__sizeof__', '__str__', '__sub__', '__subclasshook__', 'astimezone', 'combine', 'ctime', 'date', 'day', 'dst', 'fold', 'fromisocalendar', 'fromisoformat', 'fromordinal', 'fromtimestamp', 'hour', 'isocalendar', 'isoformat', 'isoweekday', 'max', 'microsecond', 'min', 'minute', 'month', 'replace', 'resolution', 'second', 'strftime', 'strptime', 'time', 'timestamp', 'timetuple', 'timetz', 'today', 'toordinal', 'tzinfo', 'tzname', 'utcfromtimestamp', 'utcnow', 'utcoffset', 'utctimetuple', 'weekday', 'year']

Conclusion

The attributeerror module datetime has no attribute now error can be frustrating to encounter, but there are several potential solutions.Python projects.

Try calling the now method on the datetime class, import the datetime class from the datetime module, and use an alias in import statement. With some patience and persistence, you should be able to resolve the issue and get back to using datetime now method.

We hope that this article has provided you with the information you need to fix this error and continue working with Python.

How to Solve Python AttributeError: module ‘datetime’ has no attribute ‘now’

This error occurs when you import the datetime module and try to call the now() method on the imported module. You can solve this error by importing the datetime class using from datetime import datetime or access the class method using

This tutorial will go through the error and how to solve it with code examples.

AttributeError: module ‘datetime’ has no attribute ‘now’

AttributeError occurs in a Python program when we try to access an attribute (method or property) that does not exist for a particular object. datetime is a built-in Python module that supplies classes for manipulating dates and times. One of the classes in datetime is called datetime. It can be unclear when both the module and one of the classes share the same name. If you use the import syntax:

You are importing the datetime module, not the datetime class. We can verify that we are importing the module using the type() function:

import datetime print(type(datetime))

We can check what names are under datetime using dir() as follows:

import datetime attributes = dir(datetime) print('now' in attributes)

In the above code, we assign the list of attributes returned by dir() to the variable name attributes. We then check for the now() attribute in the list using the in operator. When we run this code, we see it returns False.

However, if we import the datetime class and call dir() , we will see now as an attribute of the class. We can check for now in the list of attributes as follows:

from datetime import datetime attributes = dir(datetime) print('now' in attributes)

Example

Consider the following example, where we want to get the current local date and time.

import datetime date = datetime.now()

Let’s run the code to see the result:

--------------------------------------------------------------------------- AttributeError Traceback (most recent call last) Input In [2], in () ----> 1 date = datetime.now() AttributeError: module 'datetime' has no attribute 'now'

The error occurs because we imported the module datetime and tried to call the now() method, but now() is an attribute of the datetime class, not the module.

Solution #1: Use the from keyword

We can solve this error by importing the datetime class using the from keyword. Let’s look at the revised code:

from datetime import datetime date = datetime.now() print(date)

Let’s run the code to see the result:

We successfully retrieved the current date and time.

Solution #2: Use datetime.datetime

We can also solve this error by importing the module and then accessing the class attribute using datetime.datetime , then we can call the now() method. Let’s look at the revised code:

import datetime date = datetime.datetime.now() print(date)

Let’s run the code to see the result:

We successfully retrieved the current date and time.

Summary

Congratulations on reading to the end of this tutorial! Remember that from datetime import datetime imports the datetime class and import datetime imports the datetime module.

How to fix the «AttributeError: module ‘datetime’ has no attribute ‘now'» in Python

If you are facing the Python Attribute Error that says «AttributeError: module ‘datetime’ has no attribute ‘now'», this article will help you understand why this error occurred and how to fix it. I will be giving also sample scripts that simulate the error to occur and explain why and solve it.

Why does «AttributeError: module ‘datetime’ has no attribute ‘now'» occurs?

The «AttributeError: module ‘datetime’ has no attribute ‘now’ tells you that the module known as datetime has no attribute called now. It is because we are trying to output the current date and time straight after the datetime.

Here’s a simple and best sample that simulates the scenario

The script above shows that the datetime module is being imported to the Python file script and trying to output the current date and time using the now attribute directly. Unfortunately, this script will return an Attribute Error stating that the said module does not have or contain a now which is actually true.

The error occurred because we are trying to get the current date and time directly from the module which should not be. The now method that we are trying to get is from the datetime class of the datetime module. This kind of error can be solved easily in many ways.

Solution #1: Defining the datetime class

One of these error solutions is to define the datetime class first as the attribute of the datetime module. Check out the sample script below.

The script above shows that we must get the datetime class first from the datetime module so we can call the now() method. We must understand that we just only imported the datetime module and not directly the datetime class. We can check all the attributes and methods of the datetime module by running the following script.

Solution 2: Importing the datetime

We can also solve this problem by importing only the datetime class and not the whole module. To do that we can do something like the following.

This time we can now directly call the now() method because we only imported the datetime class. We can also make an alias for the datetime class like the following.

If you try to execute the following Python script, you will spot the difference.

Importing the Module

Importing the Class

There you go! That is how you can solve the «AttributeError: module ‘datetime’ has no attribute ‘now'» Python error and how you can prevent it from occurring in your current and future projects.
