We can use the built-in zip() function in Python to process multiple sequences in parallel.

zip() grabs the item from each sequence that has the same index value and creates a new tuple from them.

players = ['Messi', 'Ronaldo', 'Neymar', 'Salah']

goals = [10, 12, 8]

print(zip(players, goals))
# <zip object at 0x000001B1E6624800>

players = ['Messi', 'Ronaldo', 'Neymar']

goals = [10, 12, 8]

for player, goal in zip(players, goals):
    print(f"{player} - {goal}")

# Messi - 10
# Ronaldo - 12
# Neymar - 8

In our code example above, both the lists - players and goals had the same number of elements.

What happens when we provide two or more sequences with different numbers of elements to the zip() function?

In such a scenario, zip() will automatically stop processing the sequences when it reaches the end of the shortest sequence.

players = ['Messi', 'Ronaldo', 'Neymar', 'Salah'] # 4 elements

goals = [10, 12, 8] # 3 elements

for player, goal in zip(players, goals):
    print(f"{player} - {goal}")

# Messi - 10
# Ronaldo - 12
# Neymar - 8
