Let’s say I have to check whether the “Data” substring is present in “Welcome to the Data Science Learner” or not then I will use “in” operator to check.

my_string = "Welcome to the Data Science Learner"
print("Data" in my_string)

Output

True

The statement “Data” in my_string will return True or False depending on the match of the substring.

You can also use the “in ” operator in the if-else or another loop. It will act as the condition for that loop.

my_string = "Welcome to the Data Science Learner"
if "Data" in my_string:
    print("Substring exists in String")
else:
    print("Substring not exists in String")

OutputUsing the in operator for the statment checking in the loop
