Python | Padding a string upto fixed length
Given a string, the task is to pad string up to given specific length with whitespaces. Let’s discuss few methods to solve the given task.
Method #1: Using ljust()
# Python code to demonstrate# pad spaces in string# upto fixed length # initialising stringini_string = "123abcjw"padding_size = 15 # printing string and its lengthprint ("initial string : ", ini_string, len(ini_string)) # code to pad spaces in stringres = ini_string.ljust(padding_size) # printing string and its lengthprint ("final string : ", res, len(res)) |
Output:
initial string : 123abcjw 8 final string : 123abcjw 15
Method #2: Using format
# Python code to demonstrate# pad spaces in string# upto fixed length # initialising stringini_string = "123abcjw" # printing string and its lengthprint ("initial string : ", ini_string, len(ini_string)) # code to pad spaces in stringres = "{:<15}".format(ini_string) # printing string and its lengthprint ("final string : ", res, len(res)) |
Output:
initial string : 123abcjw 8 final string : 123abcjw 15
Method #3: Using operators( * and +)
# Python code to demonstrate# pad spaces in string# upto fixed length # initialising stringini_string = "123abcjw"padding_size = 15 # printing string and its lengthprint ("initial string : ", ini_string, len(ini_string)) # code to pad spaces in stringres = ini_string + " "*(padding_size - len(ini_string)) # printing string and its lengthprint ("final string : ", res, len(res)) |
Output:
initial string : 123abcjw 8 final string : 123abcjw 15
