In Python, a char can either be defined as an ASCII value or, if the char carries digits only, as the number it represents. In ASCII, a particular numerical value is given to different characters and symbols for computers to store and manipulate.
To find an ASCII value of a character, use the ord[] function. Let’s see how to convert ASCII value to character value.
To convert int to char in Python, use the chr[] method. The chr[] is a built-in Python method that returns a character [a string] from an integer [it represents the Unicode code point of the character].
Syntax
chr[i]
Arguments
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
Let’s use the chr[] function to convert int to a character.
print[chr[97]] print[chr[65]] print[chr[1100]]
Output
a A ь
And we get the characters the output concerning its ASCII value. The chr[] method returns a character whose Unicode point is num, an integer.
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].
print[chr[-11]]
Output
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]An integer we have passed is outside the range, and then the method returns a ValueError.
Convert a list of integers to characters
To create a list in Python, 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]Output
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 Python char to int
To convert char to int in Python, use the ord[] method. The ord[] is a built-in Python function that returns a number representing the Unicode code of a specified character.
print[ord['K']] print[ord['B']] print[ord['#']] print[ord['~']]
Output
75 66 35 126
Conclusion
To convert int to character, use the chr[] function. To convert integer to character, use the ord[] function.

In Python an integer can be converted into a string using the built-in str[] function. The str[] function takes in any python data type and converts it into a string. But use of the str[] is not the only way to do so. This type of conversion can also be done using the “%s” keyword, the .formatfunction or using f-stringfunction.
Below is the list of possible ways to convert an integer to string in python:
1. Using str[] function
Syntax: str[integer_value]
Example:
Python3
num = 10
print["Type of variable before convertion : ", type[num]]
converted_num = str[num]
print["Type After convertion : ",type[converted_num]]
Output:
Type of variable before convertion : Type After convertion :
2. Using “%s” keyword
Syntax: “%s” % integer
Example:
Python3
num =
10
print["Type of variable before convertion : ", type[num]]
converted_num = "% s" % num
print["Type after convertion : ", type[converted_num]]
Output:
Type of variable before convertion : Type after convertion :
3. Using .format[] function
Syntax: ‘{}’.format[integer]
Example:
Python3
num = 10
print["Type before convertion : ", type[num]]
converted_num = "{}".format[num]
print["Type after convertion :",type[converted_num]]
Output:
Type before convertion : Type after convertion :
4. Using f-string
Syntax: f'{integer}’
Example:
Python3
num = 10
print["Type before convertion : ",type[num]]
converted_num = f'{num}'
print["Type after convetion : ", type[converted_num]]
Output:
Type before convertion : Type after convetion :
5. Using __str__[] method
Syntax: Integer.__str__[]
Python3
num = 10
print["Type before convertion : ",type[num]]
converted_num = num.__str__[]
print["Type after convetion : ", type[converted_num]]
Output:
Type before convertion : Type after convetion :
