python - 将理解列表打印为字符串

Question

假设我有一个理解列表:

list1 = [("hello","my name"),("is","hayhay")]

我如何使用循环将其打印出来？我试过做

for line in list1:
   print(line);

但它不起作用。

Answer 1

如果你想打印每个元组:

for i in list1:
    print(i)

('hello', 'my name')
('is', 'hayhay')

如果要打印为一系列字符串:

for i in list1:
    for l in i:
        print(l)

hello
my name
is
hayhay

如果要打印成统一字符串:

list2 = ""
for i in list1:
    for l in i:
        list2 += l+" "
print(list2)

hello my name is hayhay
