将字符串添加到列表中的每个单独的字符串

Question

简单地添加字符串和字符串列表会产生错误cannot concatenate 'str' and 'list' objects。是否有更优雅的方式来执行以下操作（例如，没有循环）？

list_of_strings = ["Hello", "World"]
string_to_add = "Foo"

for item, string in enumerate(list_of_strings):
    list_of_strings[item] = string_to_add + string

# list_of_strings is now ["FooHello", "FooWorld"]

Answer 1

使用理解：

list_of_strings = [s + string_to_add for s in list_of_strings]

Answer 2

尝试使用地图

list_of_strings = ["Hello", "World"]
string_to_add = "Foo"


print map(lambda x:string_to_add+x,list_of_strings)
