Replace the single quote (') character from a string

Question

I need to strip the character "'" from a string in python. How do I do this?

I know there is a simple answer. Really what I am looking for is how to write ' in my code. for example n = newline.

Answer 1

As for how to represent a single apostrophe as a string in Python, you can simply surround it with double quotes ("'") or you can escape it inside single quotes (''').

To remove apostrophes from a string, a simple approach is to just replace the apostrophe character with an empty string:

>>> "didn't".replace("'", "")
'didnt'

Answer 2

Do you mean like this?

>>> mystring = "This isn't the right place to have "'" (single quotes)"
>>> mystring
'This isn't the right place to have "'" (single quotes)'
>>> newstring = mystring.replace("'", "")
>>> newstring
'This isnt the right place to have "" (single quotes)'

You can escape the apostrophe with a character as well:

mystring.replace(''', '')

Here are a few ways of removing a single ' from a string in python.

str.replace

replace is usually used to return a string with all the instances of the substring replaced.
```
"A single ' char".replace("'","")
```
str.translate

In Python 2

To remove characters you can pass the first argument to the funstion with all the substrings to be removed as second.
```
"A single ' char".translate(None,"'")
```
In Python 3

You will have to use str.maketrans
```
"A single ' char".translate(str.maketrans({"'":None}))
```
re.sub

Regular Expressions using re are even more powerful (but slow) and can be used to replace characters that match a particular regex rather than a substring.
```
re.sub("'","","A single ' char")
```

Other Ways

There are a few other ways that can be used but are not at all recommended. (Just to learn new ways). Here we have the given string as a variable string.

Using list comprehension

''.join([c for c in string if c != "'"])

Using generator Expression
```
''.join(c for c in string if c != "'")
```

Another final method can be used also (Again not recommended – works only if there is only one occurrence )

Using list call along with remove and join.

x = list(string)
x.remove("'")
''.join(x)

I met that problem in codewars, so I created temporary solution

pred = "aren't"
pred = pred.replace("'", "99o")
pred = pred.title()
pred = pred.replace("99O", "'")
print(pred)

You can use another char combination, like 123456k and etc., but the last char should be letter
