Method # 1: Using ljust()
| # Python code for demo
# spaces in the line
# to a fixed length
# initialization string ini_string = "123abcjw" padding_size = 15
# print string and its length print ( "initial string:" , ini_string, len (ini_s tring))
# code to fill in spaces in a line res = ini_string.ljust (padding_size)
# print line and its length print ( "final string:" , res, len (res)) |
Exit :
initial string: 123abcjw 8 final string: 123abcjw 15
Method # 2: Using format
| # Python code for demonstration
# spaces in the line
# up to fixed length
# initializing string ini_string = "123abcjw"
# print line and its length print ( "initial string:" , ini_string, len (ini_string))
# code to fill in spaces in a line res = "{: "15}" . format (ini_string) # print line and its length print ( "final string:" , res, len (res)) |
Output:
initial string: 123abcjw 8 final string: 123abcjw 15
Method # 3: Using the (* and +) operators
| # Python code for demonstration
# line spaces
# to a fixed length
# initialization string ini_string = "123abcjw" padd ing_size = 15
# print line and its length print ( "initial string:" , ini_string, len (ini_string))
# code to fill in spaces in a line res = ini_string + "" * (padding_size - len (ini_string))
# print line and its length print ( "final string:" , res, len (res)) |
Exit:
initial string: 123abcjw 8 final string: 123abcjw 15
