I created a zip object using the following line of code:
k=zip([1,2,3],['a','b','c'])
Converting this into a list gives the output:
[(1,'a'),(2,'b'),(3,'c')]
However, when I use this line of code
x,y=zip(*k)
it gives me this ValueError:
"ValueError: not enough values to unpack (expected 2, got 0)"
I've been trying to find out what the problem is but couldn't figure anything out.
Method zip returns a iterator, so when you print it, you consume it so after that k is empty
apply the second zip directly
k = zip([1,2,3],['a','b','c'])
x,y = zip(*k)
print(x, "/", y) # (1, 2, 3) / ('a', 'b', 'c')
wrap it in a list to use it multiple times
k = list(zip([1,2,3],['a','b','c']))
print(k) # [(1, 'a'), (2, 'b'), (3, 'c')]
x,y = zip(*k)
print(x, "/", y) # (1, 2, 3) / ('a', 'b', 'c')
