TypeError: unsupported operand type(s) for +: 'int' and 'str'

Answer 3

You are literally adding two impossible things. A string and an integer.

Like saying you're adding
a + 1

Technically the computer does not know how to add so it throws an error. The best way to solve is to change all to a common data type. Either all as integers or either all as a string.

int() for changing it to integers
str() for changing to strings.

Answer 4

You can fix the error by either using str() or int():
str(1) + '2' + str(3) + '4'
>>>'1234'
1 + int('2') + 3 + int('4')
>>>10

Answer 5

Thanks
