TypeError: not enough arguments for format string when using %s

Question

this is my code

import sys
name = input(\"Enter your name:\")
last_name = input(\"Enter your last name:\")
gender = input(\"Enter your gender:\")
age = input         


        

Answer 1

You need to put your arguments for string formatting in parenthesis:

print (... % (name, last_name, gender, age))

Otherwise, Python will only see name as an argument for string formatting and the rest as arguments for the print function.

Note however that using % for string formatting operations is frowned upon these days. The modern approach is to use str.format:

print ("So your name is {}, your last name is {}, you are {} and you are {} years old".format(name, last_name, gender, age))

Answer 2

You need a set of parenthesis:

>>> '%s %s' % 'a', 'b'  # what you have
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: not enough arguments for format string
>>>
>>>
>>> '%s %s' % ('a', 'b')  # correct solution
'a b'

'%s %s' % 'a', 'b' is evaluated as ('%s %s' % 'a'), 'b', which produces an error in '%s %s' % 'a' since you have fewer arguments than format specifiers.

print("So your name is %s, your last name is %s, you are %s and you are %s years old" % (name, last_name, gender, age))
