Hey Bharti,

You can get some idea from the below example. 

• This mainly happens with functions return different data types according to the parameters given. The best way to avoid this is to use type() function to determine the return value’s data type and act accordingly

1. x = fun() #function whose return data type is unknown

2. if type(x) == int:#if the return value is an integer

3. #do this

4. elif type(x) == str:#if the return value is a string

5. #do this

If the error has occurred inside the function you need to check your code to ensure it’s working properly.

More about non-subscriptable error (TypeError)

Python will throw a TypeError if you try to access a non-subscriptable in a way that you access a string or array object (or any other type of subscriptable object) .

Here a string object subscripted

1. >>> x = 'this is subscriptable'

2. >>> x[0]

3. >>> 't'

Some common non-subscriptable object types are int, float, bool and None

1. >>> y = 123 #an integer

2. >>> y[0] # will result an error

3. Traceback (most recent call last):

4. File "<pyshell#29>", line 1, in <module>

5. y[0]

6. TypeError: 'int' object is not subscriptable

7. >>>

This type of errors happen when you use the same variable to store different type of data types throughout your code and you eventually lost track of the data type the variable currently has.

The solution is either to check the variable carefully throughout the code or to use different variables to store values with different data types if memory usage is not an issue.

Example:

1. >>> x = '10' #x is a string

2. >>> print(x)

3. 10

4. >>> x = int(x) #x is now a int

5. >>> print(x)

6. 10

7. >>> x[0] # will result an error

8. Traceback (most recent call last):

9. File "<pyshell#29>", line 1, in <module>

10. y[0]

11. TypeError: 'int' object is not subscriptable

12. >>>
