Python:将单个元素与列表中的每个元素配对

Question

例如:myStr = 'z' 与 myList = ['a','b','c'] 配对，输出如下:

['z','a']
['z','b']
['z','c']

单线会很棒!

我试着这样做:

print zip([myStr, x] for x in myList)

但输出并不完全如我所愿，如下所示:

[(['z', 'a'],), (['z', 'b'],), (['z', 'c'],)]

Answer 1

试试这个:

myList = ['a','b','c']
myStr = 'z'
res = [[myStr, x] for x in myList]
