Shorten dict comprehension with repeated operation

Question

dc = {line.split('=')[0]: line.split('=')[1] for line in txt}

Below avoids duplication but is even longer:

dc = {k: v for line in txt for k, v in
      zip(*map(lambda x: [x], line.split('=')))}

Any better way? Just without any imports.

Context: with open('config.txt', 'r') as f: txt = f.read().split('\n')

a=1
bc=sea

>>> {'a': '1', 'bc': 'sea'}  # desired output; values should be string

Answer 1

dc = dict(line.split('=') for line in txt)

Answer 2

This is one of the types of problems that the walrus operator := can handle:

dc = {(s := line.split('='))[0]: s[1] for line in txt}

Of course, in this case there's a much cleaner solution.

Answer 3

{k: v for line in txt for k, v in [line.split('=')]}

Advantage over superb rain's answer is ability to modify k and v if needed. Slight memory & speed advantage by avoiding allocation via a generator (credit @GZ0):

{k: v for k, v in (line.split('=') for line in txt)}
