It’s 2024, the year of the linux desktop, and the best™
way to debug computer programs is still the good ol’ print
statement.
Since Python 3.6 it is possible to use f-strings.
One of my favorite ways to use them for debugging is with the equal
sign
(=
):
To display both the expression text and its value after evaluation, (useful in debugging), an equal sign
'='
may be added after the expression.
Here is one example:
def is_full_word_match(token, words):
print(f' is_full_word_match: {token=} {words=}')
return token in words
If you call it like so:
is_full_word_match("hello", "hello world")
Then it will print the following:
is_full_word_match: token='hello' words='hello world'
This is a more ergonomic (and quicker) way to write than the classic:
print(' is_full_word_match: token=' + token + ' words=' + words)
Or even:
print(' is_full_word_match: token={} words={}'.format(token, words))
