Let’s say we have two Python files in the same directory:,importlib — Python 3 documentation,The import system — Python 3 documentation,»module» — Glossary — Python 3 documentation

There is even a variant to import all names that a module defines:,If the module is imported, the code is not run:,An alternative way of importing the submodule is:,Now enter the Python interpreter and import this module with the following command:

# Fibonacci numbers module def fib(n): # write Fibonacci series up to n a, b = 0, 1 while a < n: print(a, end=' ') a, b = b, a+b print() def fib2(n): # return Fibonacci series up to n result = [] a, b = 0, 1 while a < n: result.append(a) a, b = b, a+b return result

In order to source a Python file from another python file, you have to use it like a module. import the file you want to run and run its functions. For example, say you want to import fileB.py into fileA.py, assuming the files are in the same directory, inside fileA you'd write,How to move a file from one folder to another using Python?,In file B you have to define a function called my_func before you can use it in any other file.,How to read data from one file and print to another file in Java?

Now in fileA, you can call any function inside fileB like:

Example

def my_func(): print("Hello from B")

Now when you run fileA.py, you will get the output:

Create another Python file and import the previous Python file into it.,Create a Python file containing the required functions.,To import only required functions defined in a Python file:Syntax: ,Both files are imported into an another Python file named file.py.

Just like with regular Python you can import and use code from files in your own MicroPython scripts. This is great for breaking a large or complex script into smaller pieces, or for sharing and reusing code with multiple projects.,We'll start by looking at how to import code from a single .py file in your MicroPython script. First make sure you have a board running MicroPython and are familiar with copying files to and from the board.,Next start by creating a simple Python file with a few functions on your computer. In a text editor create test.py and fill it with the following code:,If, for any reason, you would like to unsubscribe from the Notification List for this product you will find details of how to do so in the e-mail that has just been sent to you!

Python include another file in python code example

Solution 1: If your file structure is as follows: In this case, your files can be empty , if you like (or they can define any number of things - see this fine answer from Alex Martelli for more details. And, the regular expression based solution given by Rob above seems like a good one to me.

How to include class from another file(in another folder)

If your file structure is as follows:

myproject/ __init__.py call_participant.py lib/ __init__.py lib_add_participant.py 

In this case, your __init__.py files can be empty , if you like (or they can define any number of things - see this fine answer from Alex Martelli for more details.

then you can add it by using

from .lib.lib_add_participant import LibAddParticipant 

However, if call_participant.py is your end script, then this tactic will not work, because you "can't do a relative import in a non-package", as the interpreter will tell you. In that case, your best bet (in my opinion, at least) is to make lib into a package in your python path (either in your site-packages directory, or in a path referred to by your pythonpath environment variable).

Assuming lib is in a directory listed in your PYTHONPATH , try

from lib.lib_add_participant import LibAddParticipant 

Python using variables from another file, It’s called importing. If this is data.py: verb_list = [ 'run', 'walk', 'skip', ] and this is foo.py: #!/usr/bin/env python2.7 import data print data.verb_list. Then running foo.py will access verb_list from data.py. You might want to work through the Modules section of the Python tutorial. If verb_list is stored in a script that you want to

How to include external code in Python similar as %include in SAS?

Take a look at the import statement.

You can save your variables in def_var.py as:

var_list= ['date_of_birth_year_month' ,'zip5' ,'zip4' ,'state_province' ,'city' ,'zip5_ip' ,'zip4_ip' ,'create_user' ,'create_dt' ,'update_user' ,'update_dt' ,'resp_ST' ,'resp_HomeTheater' ,'resp_Headphone'] 

And import it in your main.py :

from def_var import var_list # now you can work with your list print(var_list[1]) 

Python - Copy contents of one file to another file, Last Updated : 22 Nov, 2021. Given two text files, the task is to write a Python program to copy contents of the first file into the second file. The text files which are going to be used are second.txt and first.txt: Method #1: Using File handling to read and append. We will open first.txt in ‘r’ mode and will read …

Writing from file to another file in Python from certain set of characters to another one

I'd use a regular expression, and re.findall() :

with open('/tmp/in') as input_file: with open('/tmp/out', 'w') as output_file: input = input_file.read() output_file.write(''.join(re.findall(r'(?s)(?<=<<).*?(?=>>)', input))) 

• The with lines open the relevant data files. You probably already have this.
• The input_file.read() creates a single string with the contents of the file.
• The call to re.findall() searches for:
  • The shortest ( (?s) ) possible match until >> ( .*? )
  • >> , but excludes it from the result ( (?=>>) )

  Or consider using something like the following:

  import sys def save_lines(infile, outfile): save = False for line in infile: if save: pos = line.find('>>') if pos > -1: outfile.write(line[:pos] + '\n') save = False else: outfile.write(line) else: pos = line.find(' <<') if pos >-1: outfile.write('-----\n') save = True outfile.write(line[pos + 2:]) else: pass def test(): infile = open('tmp01.txt', 'r') save_lines(infile, sys.stdout) infile.close() if __name__ == '__main__': test() 

  Rob is right. The above solution has problems.

  And, the regular expression based solution given by Rob above seems like a good one to me.

  Here is a variation on that:

  def save_lines(infile, outfile): bracket_pattern = re.compile(r'>', re.DOTALL) content = infile.read() for mo in bracket_pattern.finditer(content): outchars = mo.group(1) outfile.write('matched: "<>" at position <>\n'.format( outchars, mo.start())) 

  However, depending on your needs, you might also want to think about the following: (1) A regular expression based approach provides very little flexibility for syntax error checking. (2) Regular expressions do not support recursive grammars, that is, if the syntax you need to parse (and we are talking about a parsing problem) here contains or is expanded to contain nested syntactic elements, a regular expression will not help.

  Here is another solution based on an FSM (finite state machine). It might give a bit more flexibility for error reporting. But, it is much longer and much more complex. That complexity has costs: (1) development time (the regular expression solution above took me 10~15 minutes; this FSM solution took me several hours); and (2) debugging (there's lots of logic, if-statements mostly) since there are lots of ways it can go wrong.

  Because it is based on an FSM, it also could not be extended (without difficultly) to support a grammar that handles nested (recursive) constructs. For that you might want to look at a parser generator. See this for a list: https://wiki.python.org/moin/LanguageParsing

  On the positive side, because the code below is based on an FSM, you can draw a state transition diagram to clarify what action that code is suppose to take in any given situation (for example, just seen a left-curly-bracket, inside curly-brackets and just seen a right-curly-bracket, etc). On paper, I drew that diagram as a digraph (circles for states, arrows between the circles for transitions). I don't think I can do the ascii-art for that, so here is what a text representation of a state transition diagram might look like:

  start: [any] --> outside outside: " seen_left [any] --> outside seen_left: " inside [any] --> outside inside: ">" --> seen_right [any] --> inside [etc]
