Verify the data type

Try to confirm that the variable or even expression that is used in the ‘in’ operator is indeed iterable.

Debugging

You can try to use debugging techniques such as printing intermediate values or even you can use a debugger to inspect the variables and expressions involved in the “in” operation.

Here is an example given of how you can troubleshoot and resolve or fix the issue in Python programming language coding:-

# Example code with error
Keyword = ‘Python’
Text = ‘Python is a popular programming language’
# Check if keyword is in the text (incorrect usage)
If keyword in text:
    Print(f’{keyword} found in the text’)
# Error message: TypeError: ‘in ’ requires string as left operand, not int
# Corrected code:
# Convert text to a list of words
Word_list = text.split()
# Check if keyword is in the list of words
If keyword in word_list:
    Print(f’{keyword} found in the text’)
