Question

我有一份清单,包括les,我想通过每个图章,作为论点:

mylist = [(a, b), (c, d), (e, f)]

myfunc(a, b)
myfunc(c, d)
myfunc(e, f)

我如何这样做?

Answer 1

这实际上非常简单,可在沙尔进行,简单地排在名单之上,并利用间谍操作员(*)将图解作为职能的理由:

mylist = [(a, b), (c, d), (e, f)]
for args in mylist:
    myfunc(*args)

E.g:

>>> numbers = [(1, 2), (3, 4), (5, 6)]
>>> for args in numbers:
...     print(*args)
... 
1 2
3 4
5 6

Answer 2

明确提出@DSM的意见:

>>> from itertools import starmap
>>> list(starmap(print, ((1,2), (3,4), (5,6)))) 
#  list  is used here to force the generator to run out.
# You could instead just iterate like `for _ in starmap(...): pass`, etc.
1 2
3 4
5 6
[None, None, None] # the actual created list;
# `print` returns `None` after printing.
