On July 1st, a change to Reddit's API pricing will come into effect. Several developers of commercial third-party apps have announced that this change will compel them to shut down their apps. At least one accessibility-focused non-commercial third party app will continue to be available free of charge. If you want to express your strong disagreement with the API pricing change or with Reddit's response to the backlash, you may want to consider the following options: Limiting your involvement with Reddit, or Temporarily refraining from using Reddit Cancelling your subscription of Reddit Premium as a way to voice your protest.

October 18, 2023Using replace() method
Strings are immutable. That is to say, after they've been created they cannot be modified. If you want to change them anyway, you have to make a copy that contains the changes you want. That's what .replace() does; it makes a new string that is a copy of the original with some portions of it replaced. As for why strings are immutable; there's a StackOverflow thread about that subject . On the other hand, lists are mutable (like most things). You can add, delete, modify, and rearrange its contents all you want, without having to create a new list to do it. So instead of creating a new list, .sort() just modifies the list in-place.

February 27, 2024Str.replace of a set of characters - Ideas - Discussions on Python.org
I would like str.replace, when given a set of characters, to replace occurrence of any of the characters in the set. I.e. 'ASDFGH'.replace(set('SFH'), '') == 'ADG' should then hold. It would mean I would not have to go to the trouble of using the re module for a common string operation. More on discuss.python.org

October 18, 2024 - Replacing characters in a string with a list comprehension? That sounds awkward! Actually, it isn’t because it’s one of the three steps required in total: ... To convert a string to a list, use the split() method with this generic syntax. string_variable = 'your string here' list_of_words = string_variable.split() Now, list comprehension. It’s a Python method of creating a new list by applying an expression to each item in a list.

There's no need to use replace for this.
What you have is a encoded string (using the string_escape encoding) and you want to decode it:
>>> s = r"Escaped\nNewline"
>>> print s
Escaped\nNewline
>>> s.decode('string_escape')
'Escaped\nNewline'
>>> print s.decode('string_escape')
Escaped
Newline
>>> "a\\nb".decode('string_escape')
'a\nb'
In Python 3:
>>> import codecs
>>> codecs.decode('\\n\\x21', 'unicode_escape')
'\n!'

You are missing, that \ is the escape character.
Look here: http://docs.python.org/reference/lexical_analysis.html at 2.4.1 "Escape Sequence"
Most importantly \n is a newline character. And \\ is an escaped escape character :D
>>> a = 'a\\\\nb'
>>> a
'a\\\\nb'
>>> print a
a\\nb
>>> a.replace('\\\\', '\\')
'a\\nb'
>>> print a.replace('\\\\', '\\')
a\nb

str.replace replaces all instances of the search string with the replacement string, which isn't what you want the correct solution would be to turn the string into a list, update the value at the wanted index and then "".join(char_list) to rebuild the string

You might consider using the index notation to build the new string out of substrings, something like this: str3 = str1[0:3] + str2[4] + str1[5:]

r/learnpython on Reddit: Using replace() method
February 27, 2024 -
Hi guys, I had a quick question about the exercise I was working on.
For using the replace() method and printing the result, we have to assign it to another variable and print that new variable.
sentence = sentence.replace(‘hey’, ‘hi’) print(sentence)
But for something such as the sort method we don’t need to assign it to a new variable and just use it straight up.
list = […] list.sort() print(list)
Why is it that some methods you need to assign it to a new variable, while others work while not assigning it to a new variable and the original is changed. Thank you.
Sorry about format, I’m on mobile.

Lists are mutable, strings (and ints) are not. Look it up for yourself. It has to do with the way memory is allocated.

The field_name is optionally followed by a conversion field, which is preceded by an exclamation point '!', and a format_spec, which is preceded by a colon ':'. These specify a non-default format for the replacement value. See also the Format specification mini-language section. The field_name itself begins with an arg_name that is either a number or a keyword. If it’s a number, it refers to a positional argument, and if it’s a keyword, it refers to a named keyword argument. An arg_name is treated as a number if a call to str.isdecimal() on the string would return true.
