if length of string is 1 add 0 to the beginninh in python

You can use an if statement to check if the length of the string is 1. If it is, you can concatenate a '0' to the beginning of the string using the string concatenation operator '+' or by using the string format method.

Here's an example:

main.py
string = '5'

if len(string) == 1:
    string = '0' + string  # using concatenation operator
    
# or

string = '{:0>2}'.format(string)  # using string format method with zero-fill
    
print(string)  # prints '05'
216 chars
11 lines

In both cases, the output will be '05' since we added a '0' to the beginning of the string.
