Fix the Error “typeerror: ‘str’ object cannot be interpreted as an integer”

Python is an ideal programing language for creating web applications and websites. Programmers and developers use Python to build various applications extensively.  It is an easy-to-program language that is written with simple syntax. The ease of coding makes it even more popular among beginners. When you are working with Python, you may experience “typeerror: ‘str’ object cannot be interpreted as an integer”.

How the error occurs

When you are creating a Python project, you land up in the error warning. This is what appears:

Traceback (most recent call last):
  File "C:/Python33/harj4.py", line 6, in <module>
    for i in range(x,y):
TypeError: 'str' object cannot be interpreted as an integer

The script you tried:

x = input("Give starting number: ")
y = input("Give ending number: ")

for i in range(x,y):
 print(i)

You may want to print something like the following assigning 3 to x and 14 to y:

Give starting number: 4
Give ending number: 13
4
5
6
7
8
9
10
11
12
13

After all this, you end up with the error warning. Let’s check out the next section to know how you simply fix the error

Solutions To Fix the Error “typeerror: ‘str’ object cannot be interpreted as an integer”

The range() accepts only integer values, and if it doesn’t have int as a parameter you are likely to get the TypeError. To help you out, we bring the best possible solutions to tackle the error. Take a look at them

Solution 1 – Parse String into an integer

The first option you can try out is to parse the string into an integer. You can do it like this

x = input("Give starting number: ")
y = input("Give ending number: ")

x = int(x)  # parse string into an integer
y = int(y)  # parse string into an integer

for i in range(x,y):
    print(i)

You get a raw input (string) by input. Int is added, which is used to parse into an integer. You get an error as a result if no valid string is held by the string. You can even get it more refined with the help of try/except statements.

Solution 2 – Use int()

Another way to solve the error warning, you need to use int() in order to change the input. Use the following to remove this error:

x = int(input("Give starting number: "))
y = int(input("Give ending number: "))

for i in range(x, y):
print(i)

Output

Give starting number: 4
Give ending number: 13
4
5
6
7
8
9
10
11
12

Conclusion

We highlighted the solutions to remove the error “typeerror: ‘str’ object cannot be interpreted as an integer. You can simply implement the above solutions to resolve this TypeError. I hope you find it interesting and informative.
