python - 如何将一个列表中的每个元素乘以另一个列表中的每个元素？

Question

拿清单：

["nae", "red"]
[5, 2, 3]

使用 for 循环打印出以下内容：

"nnnnnaaaaaeeeee"
"nnaaee"
"nnnaaaeee"
"rrrrreeeeeddddd"
"rreedd"
"rrreeeddd"

---

这是我到目前为止所拥有的：

list1 = ["nae", "red"]
list2 = [5, 2, 3]

z = 0

for x in list1:
    for y in list2:
        print(list1[z]*list2[z])
        z = z + 1

Answer 1

您的解决方案的问题之一是您没有迭代每个字符串的字符。这是一个解决方案：

strings = ["nae", "red"]
mults = [5, 2, 3]

for string in strings:
    for mult in mults:
        s = ""
        for char in string:
            s += char * mult
        print(s)

输出：

nnnnnaaaaaeeeee
nnaaee
nnnaaaeee
rrrrreeeeeddddd
rreedd
rrreeeddd
