zip sequence to tuple

zip sequence to tuple

A useful tool for parallel iteration is the built-in function zip, which "zips" together the sequences, returning a list of tuples:

zip(sequence1, ...) returns a list of tuples, where each tuple contains an item from each of the supplied sequences. The returned list has the same length as the shortest of the supplied sequences.

names = ['Mike', 'Bob', 'Robert', 'Mary'] 
ages = [1, 5, 3, 2] #   w w w .j a va  2 s  .co m
print zip(names, ages) 
for name, age in zip(names, ages): 
    print name, 'is', age, 'years old' 

The code above generates the following result.

Zip three tuples

T1, T2, T3 = (1,2,3), (4,5,6), (7,8,9)
print T3

print zip(T1,T2,T3)

The code above generates the following result.

Loop over two or more sequences at the same time, the entries can be paired with the zip() function.

questions = ['A', 'B', 'C']
answers = ['a', 'b', 'c']
#   ww w .  j av a 2  s  . c om
for q, a in zip(questions, answers):
     print 'What is your %s?  It is %s.' % (q, a)

The code above generates the following result.
