Python用“单词”替换单词

Question

How can I replace word with "word" in python? I've already tried this:

str = "some_word"
str.replace("some_word", '"some_word"')

but this doesn't work

Answer 1

1) Don't use str as variable name as it is keyword in python.

d = 'ab'
print(d.replace('ab','ac'))

2) String are immutable in python so you have to re-assign it like:

d = d.replace('ab','ac')
print(d)

Answer 2

This perfectly works:

a = "some_word"
print(a) # some_word
a = a.replace("some_word", '"some_word"')
print(a) # "some_word"

If you want to wrap the entire string in double quotes, and not only a part of it, you may use one of these approaches:

a = "some_word"
a1 = '"{}"'.format(a)
a2 = '"' + a + '"'
a3 = f'"{a}"'

Answer 3

you should create a variable to receive the replaced value.

 str = "some_word"
 str = replace(old_chars, new_chars)

Answer 4

>>> strr = "some_word"
>>> strr = f'"{strr}"'
>>> print(strr)
"some_word"
