Today I get the following error Type: ‘in string’ requires string as left operand, not int in python.

How To Solve Type: ‘in string’ requires string as left operand, not int Error ?

  1. How To Solve Type: 'in string' requires string as left operand, not int Error ?

    To Solve Type: 'in string' requires string as left operand, not int Error In fact, Python only allows you to use the in operator with a right operand of type string if the left operand is also of type string:

  2. Type: 'in string' requires string as left operand, not int

Solution 1


You simply need to make cab a string:

cab = '6176'

As the error message states, you cannot do <int> in <string>:

>>> 1 in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not int
>>> 

because integers and strings are two totally different things and Python does not embrace implicit type conversion (“Explicit is better than implicit.”).

In fact, Python only allows you to use the in operator with a right operand of type string if the left operand is also of type string:

>>> '1' in '123'  # Works!
True
>>>
>>> [] in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not list
>>>
>>> 1.0 in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not float
>>>
>>> {} in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not dict
>>>
