for 循环和 a 字符串拼接就好，如果想在原列表上进行改变就这样：

1. a = ("python")    # 实际上这里 相当于  a = "python"
   
2. b = ["good","nice","great"]
   
3. for i in range(len(b)):
   
4.     b[i] = a+b[i]
   
5. 
   
6. print(b)

复制代码

重新创建个列表就这样，用列表推导式了：

1. a = ("python")
   
2. b = ["good","nice","great"]
   
3. new = [a+i for i in b]
   
4. 
   
5. print(new)

1. a = ("python")
   
2. b = ["good","nice","great"]
   
3. s = [a+b[j] for j in range(len(b))]
   
4. print(s)
