python for zip code example

Example 1: for in zip python

>>> letters = ['a', 'b', 'c']
>>> numbers = [0, 1, 2]
>>> for l, n in zip(letters, numbers):
...     print(f'Letter: {l}')
...     print(f'Number: {n}')
...
Letter: a
Number: 0
Letter: b
Number: 1
Letter: c
Number: 2

Example 2: python zip function

>>> numbers = [1, 2, 3]
>>> letters = ['a', 'b', 'c']
>>> zipped = zip(numbers, letters)
>>> zipped  # Holds an iterator object
<zip object at 0x7fa4831153c8>
>>> type(zipped)
<class 'zip'>
>>> list(zipped)
[(1, 'a'), (2, 'b'), (3, 'c')]  #list of tuples  
# zip returns tuples

Example 3: python how to download zip

url = 'https://codeload.github.com/fogleman/Minecraft/zip/master'
 
# downloading with requests
 
# import the requests library
import requests
 
 
# download the file contents in binary format
r = requests.get(url)
 
# open method to open a file on your system and write the contents
with open("minemaster1.zip", "wb") as code:
    code.write(r.content)
 
 
# downloading with urllib
 
# import the urllib library
import urllib
 
# Copy a network object to a local file
urllib.urlretrieve(url, "minemaster.zip")

Example 4: 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
