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:

If you want to remove the central character:

To replace a specific position:

To replace a specific character:

This is probably the best way:

Don’t worry about shifting characters and such. Most Python code takes place on a much higher level of abstraction.

Strings are immutable. But you can convert them to a list, which is mutable, and then convert the list back to a string after you’ve changed it.

You can also create a new string, as others have shown, by taking everything except the character you want from the existing string.

How can I remove the middle character, i.e., M from it?

You can’t, because strings in Python are immutable.

Do strings in Python end in any special character?

No. They are similar to lists of characters; the length of the list defines the length of the string, and no character acts as a terminator.

You cannot modify the existing string, so you must create a new one containing everything except the middle character.

You can partition the string, check it had the separator, than translate out lowercase letters, eg:

Other methods using the partition module don’t seem to take into account your trigger word being repeated. This example will work in the case you have ‘aBcJohnsonDeFJohnsonHiJkL’ in the event that, that particular case is of concern to you.

There are a couple of ways you could tackle this. Here’s the simplest one I could think of. The idea is to tackle it in three parts. First off, you need to know the middle string. In your case ‘Johnson.’ Then you can remove the lowercase letters from the part before and the part after.

Not exactly very simple or streamlined, but you could do this sort of thing (based partially on Zero Piraeus’)

Alternatively use re and use regular expressions. This will allow the removal of leading/trailing spaces.

Easiest way would be to simply replace it with an empty string.

If want to remove the word from only the start of the string, then you could do:

Where string is your string variable and prefix is the prefix you want to remove from your string variable.

You can also use a regexp with re.sub :

Providing you know the index value of the beginning and end of each word you wish to replace in the character array, and you only wish to replace that particular chunk of data, you could do it like this.

Alternatively, if you also wish to retain the original data structure, you could store it in a dictionary.
