How to create a Python dictionary from text file?

Assuming a following text file (dict.txt) is present

1 aaa
2 bbb
3 ccc

Following Python code reads the file using open() function. Each line as string is split at space character. First component is used as key and second as value

d = {}
with open("dict.txt") as f:
for line in f:
    (key, val) = line.split()
    d[int(key)] = val

print (d)

The output shows contents of file in dictionary form

{1: 'aaa', 2: 'bbb', 3: 'ccc'}
