zip in python list code example

Example 1: zip python

>>> x = [1, 2, 3]
>>> y = [4, 5, 6]
>>> zipped = zip(x, y)
>>> list(zipped)
[(1, 4), (2, 5), (3, 6)]
>>> x2, y2 = zip(*zip(x, y))
>>> x == list(x2) and y == list(y2)
True

Example 2: python zip a list of lists

# Basic syntax:
list(zip(*[[list], [of], [lists]]))
# Where zip is used to join iterable items together by corresponding
#	iterated elements

# Example usage 1:
list_of_lists = [[1,2], [3,4], [5,6]]
list(zip(*list_of_lists))
--> [(1, 3, 5), (2, 4, 6)] 

# Example usage 2:
list_of_lists = [[1,2], ['a',4], [5,6,7]]
list(zip(*list_of_lists))
--> [(1, 'a', 5), (2, 4, 6)] # Note that the extra element in [5, 6, 7]
#	was ignored.

Example 3: zip python

number_list = [1, 2, 3]
str_list = ['one', 'two', 'three']

# No iterables are passed
result = zip()

# Converting itertor to list
result_list = list(result)
print(result_list)

# Two iterables are passed
result = zip(number_list, str_list)

# Converting itertor to set
result_set = set(result)
print(result_set)

>>>[]
{(2, 'two'), (3, 'three'), (1, 'one')}

Example 4: zip listas python

>>> meses = ["marzo", "abril", "mayo"]
>>> estados = ["ventoso", "lluvioso", "florido y hermoso"]
>>> for mes, estado in zip(meses, estados):
...     print(mes, estado)
...
marzo ventoso
abril lluvioso
mayo florido y hermoso
