Introduction
Tuple basics
Tuples in functions
Instruction
Good job! To check if a value is present in a tuple, you can use the in operator:
user_data = ('John', 'Smith', 29, 1.85, 'British')
if 'British' in user_data:
print('We\'ve got a British citizen!')
else:
print('We don\'t have a British citizen.')
In the code above, we check if the user_data tuple contains the string 'British'.
Exercise
The train_connections variable is a list of tuples. Count the number of train connections that contain the string 'Paris'. Then, print the following information:
There are {x} train connections from/to Paris.Stuck? Here's a hint!
Iterate over the list using:
for item in train_connections:
Then, use the in operator to check if a given item (tuple) contains 'Paris'.
