zip()的目的是映射多个容器的相似索引，以便可以将它们用作单个实体使用。
用法：
zip(*iterators)
参数：
Python iterables or containers ( list, string etc )
返回值：
Returns a single iterator object, having mapped values from all the
containers.
# Python code to demonstrate the working of
# zip()
# initializing lists
name = [ "Manjeet", "Nikhil", "Shambhavi", "Astha" ]
roll_no = [ 4, 1, 3, 2 ]
marks = [ 40, 50, 60, 70 ]
# using zip() to map values
mapped = zip(name, roll_no, marks)
# converting values to print as set
mapped = set(mapped)
# printing resultant values
print ("The zipped result is:",end="")
print (mapped)输出：
The zipped result is:{('Shambhavi', 3, 60), ('Astha', 2, 70),
('Manjeet', 4, 40), ('Nikhil', 1, 50)}
如何解压缩？
解压缩意味着将压缩后的值转换回原样。这是在“*”运算符的帮助下完成的。
# Python code to demonstrate the working of
# unzip
# initializing lists
name = [ "Manjeet", "Nikhil", "Shambhavi", "Astha" ]
roll_no = [ 4, 1, 3, 2 ]
marks = [ 40, 50, 60, 70 ]
# using zip() to map values
mapped = zip(name, roll_no, marks)
# converting values to print as list
mapped = list(mapped)
# printing resultant values
print ("The zipped result is:",end="")
print (mapped)
print("\n")
# unzipping values
namz, roll_noz, marksz = zip(*mapped)
print ("The unzipped result:\n",end="")
# printing initial lists
print ("The name list is:",end="")
print (namz)
print ("The roll_no list is:",end="")
print (roll_noz)
print ("The marks list is:",end="")
print (marksz)输出：
The zipped result is:[('Manjeet', 4, 40), ('Nikhil', 1, 50),
('Shambhavi', 3, 60), ('Astha', 2, 70)]
The unzipped result:
The name list is:('Manjeet', 'Nikhil', 'Shambhavi', 'Astha')
The roll_no list is:(4, 1, 3, 2)
The marks list is:(40, 50, 60, 70)
实际应用程序：可以说有许多可能的应用程序是使用zip压缩的，无论是学生数据库还是计分卡，还是需要组映射的任何其他实用程序。下面展示了一个记分卡的小例子。
# Python code to demonstrate the application of
# zip()
# initializing list of players.
players = [ "Sachin", "Sehwag", "Gambhir", "Dravid", "Raina" ]
# initializing their scores
scores = [100, 15, 17, 28, 43 ]
# printing players and scores.
for pl, sc in zip(players, scores):
print ("Player: %s Score:%d" %(pl, sc))输出：
Player: Sachin Score:100 Player: Sehwag Score:15 Player: Gambhir Score:17 Player: Dravid Score:28 Player: Raina Score:43
