[Python] Operation of enumerate

The operation of enumerate was interesting, so I will describe it.

motion

enumerate is very useful when putting a dictionary into a for statement.

python


d = {5:1, 6:2, 7:3}

Put the above dictionary in the for statement.

python


for i, x in enumerate(d):
     print(i,x)
#0 5
1 6
2 7

If you execute enumerate from the above i has a sequence number x has a key enter.
