How to use (join) in python ?

Answer 1

You can also try this...

>>>a = list('blahblah') #create a list of every letter in the string
>>>b = '#x27;.join(a) #puts "quot; in between each letter
>>>print(b)
>>>b$l$a$h$b$l$a$h

.join() takes split up data and "glues" it together with whatever you want

Answer 2

Oh alright.

>>>b = 'cool'.split('o')
>>>print(b)
>>>['c', '', 'l']

>>>a = 'O'.join(b)
>>>print(a)
>>>cOOl

This is just an example, there are more uses.

By using split to take the lower case 'o's out it leaves us with a list of letters not including 'o' in "cool".

Then i call .join() on the string value of O, and tell that string to join together the letters in list "b".

It then "replaces" the 'o's with 'O's.

If you only have mobile, download pydroid 3 or QPython 3L.

If you have a computer, download python! It comes with its own IDE made with python.
