How to convert int to char python

How to Convert Int to Char in Python

To convert int to char in Python, you can use the “chr()” method. For example, the “ chr(97)” expression returns “a”. The chr() method returns a character (a string) from an integer (it represents the Unicode code point of the character).

Syntax

Parameters

i: The chr() method takes a single parameter which is an integer.

Return Value

The chr() function returns a character (a string) whose Unicode code point is the integer.

Example 1: How to Use chr() method

Let’s use the chr() function to convert int to a character.

print(chr(97)) print(chr(65)) print(chr(1100))

And we get the characters in the output concerning its ASCII value. For example, the chr() method returns a character whose Unicode point is num, an integer.

Example 2: Integer passed to chr() is out of the range

If we pass the negative value to the chr() function, then it returns ValueError: chr() arg not in range(0x110000).

Traceback (most recent call last): File "/Users/krunal/Desktop/code/pyt/database/app.py", line 7, in print(chr(-1)) ValueError: chr() arg not in range(0x110000)

We have passed an integer outside the range, and then the method returns a ValueError.

Example 3: Convert a list of integers to characters

To create a list in Python, you can use the [ ] and add the values inside it.

listA = [69, 72, 78, 81, 90, 99] for number in listA: char = chr(number) print("Character of ASCII value", number, "is ", char)

Character of ASCII value 69 is E Character of ASCII value 72 is H Character of ASCII value 78 is N Character of ASCII value 81 is Q Character of ASCII value 90 is Z Character of ASCII value 99 is c

Convert Integer to Char in Python

In this tutorial, we will look at how to convert an integer to a char in Python with the help of some examples. We’ll be looking at use-cases of finding the char (string) representing a character whose Unicode point is the integer.

How to convert integer to char in Python?

You can use the Python built-in chr() function to get the character represented by a particular integer in Unicode. The following is the syntax –

Pass the integer as an argument. The valid range for the integer argument is from 0 through 1,114,111 (0x10FFFF in base 16). If you pass an integer outside of this range, it will result in a ValueError .

Examples

Let’s look at some examples of using the above syntax –

Get the character represented by a number in Unicode

Let’s pass the integer 65 to the chr() function.

# integer to char ch = chr(65) # display char and its type print(ch) print(type(ch))

We get ‘A’ from the function. The number 65 points to the character ‘A’ in Unicode.

Let’s look at another example.

# integer to char ch = chr(44) # display char and its type print(ch) print(type(ch))

We get the comma character, ‘,’ for the integer 44.

You can use the Python built-in ord() function to get the corresponding integer for a character in Unicode.

# char to integer print(ord('A')) print(ord(','))

We get 65 for the character ‘A’ and 26 for the character ‘$’.

What if you pass a negative integer to the above function?

Let’s pass a negative integer to the chr() function as an argument.

# integer to char ch = chr(-65) # display char and its type print(ch) print(type(ch))

--------------------------------------------------------------------------- ValueError Traceback (most recent call last) Input In [20], in 1 # integer to char ----> 2 ch = chr(-65) 3 # display char and its type 4 print(ch) ValueError: chr() arg not in range(0x110000)

We get a ValueError . This is because the passed integer is outside the valid range of 0 through 1,114,111.

Convert a Character to an Integer and Vice Versa in Python

1. Use chr() to Convert an Integer to a Character in Python
2. Use ord() to Convert a Character to an Integer in Python

This tutorial discusses methods to convert a character to an integer and an integer to a character in Python.

Use chr() to Convert an Integer to a Character in Python

We can use the built-in function chr() to convert an integer to its character representation in Python. The below example illustrates this.

val = 97 chr_val = chr(val) print(chr_val) 

It will result in an error if you provide an invalid integer value to this. For example:

val = 1231232323 chr_val = chr(val) print(chr_val) 

--------------------------------------------------------------------------- ValueError Traceback (most recent call last) ipython-input-42-f76a9ed55c90> in module>  1 val = 1231232323 ----> 2 chr(val)  ValueError: chr() arg not in range(0x110000) 

Therefore, it is always good to put this code in a try. except block to catch the error, if any, and avoid any crash. The below example illustrates this:

val = 1231232323 try:  chr_val = chr(val)  print(chr_val) except Exception as e:  print('Error:', e) 

Error: chr() arg not in range(0x110000) 

Use ord() to Convert a Character to an Integer in Python

We can use the built-in function ord() to convert a character to an integer in Python. The below example illustrates this.

val = 'a' try:  int_val = ord(val)  print(int_val) except Exception as e:  print('Error:', e) 

The above method also catches any invalid input and prints out the error instead of crashing the code. For example:

val = 'aa' try:  int_val = ord(val)  print(int_val) except Exception as e:  print('Error:', e) 

Error: ord() expected a character, but string of length 2 found
