How to delete a character from a string using python?

 

There is a string, for example EXAMPLE

How can I remove the middle character ie M from it. I don't need the code, what I want to know is

  • Do strings in python end in any special character?
  • Which is a better way - shifting everything right to left starting from the middle character OR creation of a new string and not copying the middle character?

    • In Python, strings are immutable, so you have to create a new string. You have a few options of how to create the new string. If you want to remove the 'M' wherever it appears: 

    newstr = oldstr.replace("M", "")

    If you want to remove the central character: 

    midlen = len(oldstr)/2
newstr = oldstr[:midlen] + oldstr[midlen+1:]

    You asked if strings end with a special character. No, you are thinking like a C programmer. In Python, strings are stored with their length, so any byte value, including , can appear in a string.

    This is probably the best way: 

    original = "EXAMPLE"
removed = original.replace("M", "")

    Don't worry about shifting characters and such. Most python takes place on a much higher level of abstraction.

    To replace a specific position: 

    s = s[:pos] + s[(pos+1):]

    To replace a specific character: 

    s = s.replace('M','')
