Typeerror: 'str' object cannot be interpreted as an integer

Typeerror: ‘str’ object cannot be interpreted as an integer error occurs while typecasting str object into int type if the str objects are not numerical convertible. If there is any alphabet or special characters in the string then we can not typecast the str object to integer type object. In this article, we will explore the best ways to fix this Typeerror.

Typeerror: ‘str’ object cannot be interpreted as an integer ( Solution ) –

For better understanding lets replicate this error. Just run the below code to replicate the issue.

start="a1"
end="a3"

for i in range(start,end):
  print(i)

Typeerror 'str' object cannot be interpreted as an integer — Typeerror ‘str’ object cannot be interpreted as an integer

In the above code, we use str in the place of int type object hence if we run this code we will get this error (‘str’ object cannot be interpreted as an integer). We can solve this error in multiple ways.

Solution 1 : Cleaning the str object and make integer compatible –

This type of solution is applicable if because of wrong code implementation unexpected str object is coming. For example, suppose you are fetching the roll number from Database but by logic error , the name and roll number both are coming all together. In such type of case we can clean the input before processing and make it integer compatible.

Solution 2 : Typecasting from str to int –

If the str is compatible with int type of object then there is no requirement of cleaning we can directly convert the same into int() type. In the above example we did cleaning + typecasting and here we need to do typecasting only.

'str' object cannot be interpreted as an integer solution by typecasting — ‘str’ object cannot be interpreted as an integer solution by typecasting

Solution 3 : Using (try -except) for handling exception –

Suppose if you do not want to brake the program flow and just need to build a separate path for exceptions. Then use this try-catch block for handling these type of situation. Please follow the below code.
