zip()should only be used with unequal length inputs when you don’t care about trailing, unmatched values from the longer iterables. If those values are important, useitertools.zip_longest()instead. zip()in conjunction with the*operator can be used to unzip a list: >>> >>> x = [1,...
# create dict by dict comprehension leader_dict = {i: name for i, name in zip(id, leaders)} print(leader_dict) # {1: 'Elon Mask', 2: 'Tim Cook', 3: 'Bill Gates', 4:'Bai Li'} # create dict by dict function leader_dict_2 = dict(zip(id, leaders)) print(leader_dict_2) ...
Python文档研读系列:zip函数 This function returns a list of tuples, where the i-th tuple contains the i-th element from each of the argument sequences or iterables. The returned list is truncated in length to the length of the shortest argument sequence. When there are multiple arguments whi...

在Python中,`zip()`函数用于将可迭代对象(如列表)作为参数,将对象中对应的元素打包成一个个元组,然后返回由这些元组组成的可迭代对象。如果要垂直打印来自`zip()`的列表,可以使用`zip...

map(function, sequence[, sequence, ...]) -> list 通过定义可以看到,这个函数的第一个参数是一个函数,剩下的参数是一个或多个序列,返回值是一个集合。 function可以理解为是一个一对一或多对一函数,map的作用是以参数序列中的每一个元素调用function函数,返回包含每次function函数返回值的list。
