Sometimes, we want to do a case-insensitive string comparison with Python.
In this article, we’ll look at how to do a case-insensitive string comparison with Python.
How to do a case-insensitive string comparison with Python?
To do a case-insensitive string comparison with Python, we can convert both strings we want to compare to lower case.
For instance, we write:
string1 = 'Hello'
string2 = 'hello'
if string1.casefold() == string2.casefold():
print("The strings are the same (case insensitive)")
else:
print("The strings are NOT the same (case insensitive)")
We call the casefold method on both strings and compare them with ==.
Therefore, we should see 'The strings are the same (case insensitive)' printed since both strings are the same ignoring the case.
Conclusion
To do a case-insensitive string comparison with Python, we can convert both strings we want to compare to lower case.
