Append zeros to the end of a string

Question

I have two strings I need to make equivalent length:

str1 ='AVFGHJK'
str2 ='ADF'

I need to append some 0s to the end of str2 so it becomes length equivalent to str1:

str1 ='AVFGHJK'
str2 ='ADF0000'

Output:

str2 ='ADF0000'

I have tried to use zfill, but it adds zeros to the beginning of the string, not the end.

Answer 1

Use str.ljust fo padding char

print("ABC".ljust(8, '0'))  # ABC00000

And str.rjust for leading char

print("ABC".rjust(8, '0'))  # 00000ABC

String have the zfill method that appends zeroes to the LEFT; to add them to the right, you could reverse the string:

str2 = str2[::-1].zfill(len(str1))[::-1]

# str2
# Out[14]: 'ADF0000'

But indeed, .rjust and .ljust are more versatile!

You can just do it yourself, like that:

str1 ='AVFGHJK'
str2 ='ADF'

str2 = str2 +(len(str1) - len(str2))*'0' 

print(str2)

Output:

ADF0000
