Replace the single quote (') character from a string

I need to strip the开发者_如何学Go 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.

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'

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)

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('\'', '')

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
