Hello,
I’m having trouble understanding the following behavior and would greatly
appreciate any insight.
l = [1,2,3,4]
b=[]
for i in range(l):
print l
b.append(l)
l.pop(0)
print b
OUTPUT
[1,2,3,4]
[2,3,4]
[3,4]
[4]
[[],[],[],[]]
My confusions is the output for b. I don’t understand why it’s empty. I’m
expecting for b to equal [[1,2,3,4], [2,3,4], [3,4], [4]].
Best Regards,
Rick
