题目

代码语言：javascript复制

a = [1, 2, 3, 4, 5]
b = ["a", "b", "c", "d", "e"]
如何得出c = ["a1", "b2", "c3", "d4", "e5"]

解题思路

1. a、b两个列表长度一致，获取长度
2. 一个for循环，每次获取同下标值
3. 字符串拼接，添加到c列表

答案

代码语言：javascript复制

a = [1, 2, 3, 4, 5]
b = ["a", "b", "c", "d", "e"]
c = []
# 方案一
for i in a:
    inx = a.index(i)
    d = b[inx]
    if d != -1:
        c.append(f"{d}{i}")
print(c)

# 方案二
c = []
for i in range(0, len(a)):
    a1 = a[i]
    b1 = b[i]
    c.append(f"{b1}{a1}")
print(c)

python for循环 字符串
