Python 将字符串与列表的所有成员连接起来,并以逗号分隔显示每个显示结果

Python Concatenate string with all members of a list and display each display result separated by commas

我正在尝试做类似 "conjugator" 的事情。

假设我有一个结尾列表:

endings = ['o', 'es', 'e', 'emos', 'eis', 'em']

我有一个动词词根作为字符串:

root = "com"

我想到的方法是:

for ending in endings:
    print root + ending

输出:

como
comes
come
comemos
comeis
comem

但我想要的结果是:

como, comes, come, comemos, comeis, comem

我怎样才能做到这一点(并且每个结果项都没有引号,最后一项后没有逗号)?

您需要列表理解和 str.join(). 来自文档:

str.join(iterable)

Return a string which is the concatenation of the strings in the iterable iterable. The separator between elements is the string providing this method.

>>> root = "com"
>>> endings = ['o', 'es', 'e', 'emos', 'eis', 'em']
>>> verbs = [root + ending for ending in endings]
>>> print ", ".join(verbs)
como, comes, come, comemos, comeis, comem
