Given two lists a=[(1,11), (2,22), (3,33)] and b=[111, 222, 333] I would like to know if there is a syntactically easy-to-read solution to iterate over triples of values as follows:
for x,y,z in WANTED(a, b):
print(x, y, z)
# should iterate over (1,11,111), (2,22,222), (3,33,333)
I do know that this can be done like
for _item, z in zip(a, b):
x, y = _item
print(x, y, z)
and I also do know how to pack this into my own custom iterator, but I'd like to know if this is possible using low level built-in solutions (maybe itertools) to achieve this with syntactically easy-to-read code.
If I understand you correctly, you can do:
a = [(1, 11), (2, 22), (3, 33)]
b = [111, 222, 333]
for (x, y), z in zip(a, b): # <-- note the (x, y)
print(x, y, z)
This prints:
1 11 111
2 22 222
3 33 333
