Another most common error that occurs during code in Python is
TypeError. It is an exception in Python.
You will get this error when you use an inappropriate data type of object in an operation.
This article will show how we get a
TypeError in Python. Also, we will discuss the topic by using necessary examples and explanations to make the topic easier.
TypeError Occurs in Python
As we already discussed above, the cause of this error is the use of inappropriate data types in an operation. Suppose you have written the below Python program.
num=list(str(345678)) for i in num: print(chr(i))
When you try to run the above example, you will get an error like the one below.
Traceback (most recent call last): File "<string>", line 5, in <module> TypeError: an integer is required (got type str)
The problem in the example above is that we passed an incompatible data type inside the function
chr() on the line
Let’s see another example that produces the same error.
In this example, we will perform a divide operation on two variables. The Python code for this purpose is like below.
MyInt = 45 MyInt2 = "5" Result = MyInt / MyInt2 print("Result is : ", Result)
In our example above, we divide the integer type variable by a string type variable incompatible with this operation. So after running this example, you will get an error like the one below.
Traceback (most recent call last): File "<string>", line 3, in <module> TypeError: unsupported operand type(s) for /: 'int' and 'str'
How to Resolve the
TypeError: an integer is required
To resolve this error, we need to fix the data type. For our first example, you can fix the code as follows:
num=list(str(345678)) for i in num: print(i)
Here you can notice that we just fixed the line where the data type is incompatible with the operation, and another part of the program remains the same.
After fixing the first example, you will get an output like the one below.
3 4 5 6 7 8
Now let’s solve our second example. To fix our second example, we need to remove the double quote from the second variable like below.
MyInt = 45 MyInt2 = 5 Result = MyInt / MyInt2 print("Result is : ", Result)
And you will see that the error was resolved, and you will get the output below.
Result is : 9.0
Please take note that the commands and programs discussed here are written in the Python programming language.
