Question

我希望AH和aa同时获得两个不同的变量，可能称为cap和lowercase。

for cap, lowercase in a,b:
    print(cap+lowercase)

zip不起作用，因为它只会从A读取AH。

Answer 1

zip不起作用

实际上，如果按照你的说法使用它（给它字符串列表），它确实如此：

li_a = ['AH', 'B', 'UB']
li_b = ['aa', 'b', 'yu']

for elem_a, elem_b in zip(li_a, li_b):
    print('thing from a is {}, thing from b is {}'.format(elem_a, elem_b))

>> thing from a is AH, thing from b is aa
   thing from a is B, thing from b is b
   thing from a is UB, thing from b is yu

Answer 2

如果您希望列表中的元素具有相同的索引 a 和 b 那么你可以根据它们的索引选择值代码： -

a = ['T','UH','T']
b = ['t','oo','t']
for i in range(len(a)):
    print(a[i]+b[i])

输出： -

Tt UHoo Tt

已编辑： -

** Pythonic做同样的方式**

a = ['T','UH','T'] b = ['t','oo','t'] print (map(lambda x,y:x+y, a,b))

如何同时为2个列表使用for循环，例如a = [AH，B，UB] b = [aa，b，yu]
