Python for loop with two variables in func

Question

assume this program:
for a,b in thisFunc():
#some code
- it doesnt matter if thisFunc() has any parameters or not
Now assume that thisFunc produces two values, one goes into a and other into b, but values produced for b are less than those of a. so my question is will the for loop work perfectly fine? arnt there supposed to be errors or is there not supposed to be the use of enumerate() function required?

Answer 1

This works fine as values in [2,1] is assigned to i,j
a=[[2,1],[4,3]]
for i,j in a:
print(i,j)
but a=[1,2,3,4] will obviously give an error if you try to do the above, for that you need to use enumerate
for i,j in enumerate(a):
print(i,j)

Answer 2

You can definitely do something like this as well!
def pack(*args):
j=0
while j<len(args):
b=args[j],args[j+1]
j+=2
yield b
for a,b in pack(2,1,4,3,6,5):
print(a,b)
