Convert an integer to string in python

Now, we will see how to convert an integer to string in Python.

To convert an integer to string in python, we need to follow these below steps:

Step-1

• To convert an integer to string, We have built-in function str() which converts the argument into a string format.
• The function can take any integer as an input and it can produce a string as an output.

Step-2

• First of all, We need to take an integer value. In the below python code, You can see, I have taken the value as “123”.
• Then we need to store the string value in “value_str”.
• Now print the “value_str” and it will convert the integer to string.

Below represents the Python code to convert an Integer to String.

value=123
value_str=str(value)
value_str

Step-3

After writing the above Python code (to convert an integer to string), Ones you will print the value_str, then the output will appear as a string value ‘123’. Also, you can refer to the below screenshot.

Python convert int to bytes

To convert an integer to bytes in Python, we will use integer.to_bytes(length, byteorder) on an integer with the desired length of the array as the length is the order of the array. The byteorder is set to “big”, the order of most significant bytes starts at the beginning of the array.

Example:

my_integer = 10
c = my_integer.to_bytes(2, 'big')
print(c)

After writing the above code (python convert int to bytes), Ones you will print ” c ” then the output will appear as a “ b’\x00\n’ ”. Here, the int.to_bytes() method converts the integer to bytes. You can refer to the below screenshot python convert int to bytes.

Python convert int to bytes

This is how to convert int to bytes in Python.

Convert bytes to int in python

To convert bytes to int in python, we will use int.from_bytes() method and it will convert the bytes to an int value.

Example:

a_Bytes = b'\x00\n'
c = int.from_bytes(a_Bytes, byteorder='big')
print(c)

After writing the above code (convert bytes to int in python), Ones you will print ” c ” then the output will appear as a “ 10 ”. Here, the int.from_bytes() method converts the bytes to an integer value. You can refer to the below screenshot convert bytes to int in python.

Python convert letters to a number

Let’s see how we can convert letters to a number in python.

To convert letters to numbers will result in a list, we will use ord() for converting letters to numbers in python.

Example:

letters = 'xyza'
num = []
for letter in letters:
    number = ord(letter)-96
    num.append(number)
print(num)

After writing the above code (python convert letters to a number), Ones you will print ” num ” then the output will appear as a “ [24, 25, 26, 1] ”. Here, for loop is used to iterate over each letter in a string. In each iteration, ord(letter)-96 with letter as a current letter to an initially empty list. You can refer to the below screenshot python convert letters to a number.

Python convert letters to a number

The above Python code, we can use to convert letters to a number.

Check if a string is number python

In python, to check if all the characters are numeric we will use the method string.isnumeric() method which will return true if all the characters are number, otherwise false.

Example:

my_string = "101123"
a = my_string.isnumeric()
print(a)

After writing the above code (check if a string is number python), Ones you will print “a” then the output will appear as a “ True ”. Here, we will use isnumeric() method to check whether the string is number or not.

You can refer to the below screenshot python check if a string is number python
