String = "good"? # Type is a string.
Print("string=%s" %string) # Output print result is string=good?
Print("string=%3s" %string) # The print result is string=good (the number 3 indicates that the length of the string is 3. When the string length is greater than 3, print the result according to the string length)
print("string=%(+)6s" %string)？ # The printed result of output is string=? Ok (when the string length is less than 6, fill the space on the left side of the string to make the string length 6)
print("string=%-6s" %string)？ # The printed result is string=good? (When the string length is less than 6, fill the space on the right side of the string to make the string length 6)
