This is a Perl feature known as autovivification.

Hi all,
This is a very basic doubt. I was experimenting concept of dictionary in
python3
My problem was to find the occurance of each word in a file
f = open('hello.txt', 'r')
count = {}
for line in f:
words = line.split()
for i in words :
if i in count:
count[i] += 1
