typeerror: not all arguments converted during string formatting

Python is a versatile language that can be used for a variety of purposes from developing small scripts to creating entire applications. One of the advantages of Python is the large number of modules that are available for download from the Python Package Index (PyPI), a repository of software for the Python programming language. However, on occasion, you may encounter an error message indicating that a particular module is not found. In this blog post, we will show how to solve the error message “ typeerror: not all arguments converted during string formatting ” in Python.

 

 

What is typeerror: not all arguments converted during string formatting?

In Python, this error is raised when we use incorrect syntax for formatting a string and when we try to use the ‘%‘ operator with a number and a string. For eg.

Program:

#Here we declare variables a and b
a = 'is the'
b = 'best'

#Here we will print the string with values of a and b
print('Study Experts {0} {1}' % a, b)

Output:

 

 

 

How we can fix typeerror: not all arguments converted during string formatting in python?

For solving the type error in python we can call the ‘.format()‘ method on the string and insert the values for all placeholders.

#Here we declare variables a and b
a = 'is the'
b = 'Best.'

#Here we will print the string with values of a and b
print('Study Experts {0} {1}'.format(a, b))

Output:

 

If you wanna learn more about str.format() method then check out the documentation.

 

 

The above error also occurs when you try to use the ‘%‘ operator with an integer and a string. For eg.

#Here we declare variable string
string = '69'

result = string % 3

#Here we will print the result
print(result)

Output:

 

 

We can simply fix the above program error by converting the string type to int type.

#Here we declare variable string
string = '69'

result = int(string) % 3

#Here we will print the result
print(result)

 

 

Now the code is working fine and we can get the output.
