Subject: [Tutor] Removing characters in a string using format()

Hi there,

In one part of a program I'm writing, I want a list to be printed to the 
string. Here's my code:

# Begin snippet
listString = input('Please enter a single item: >').strip();

/        print();
         itemList.append(listString);
/

/...
/

/print('And here it is in alphabetical order:', itemList)
# End Snippet
/

However, when I print the list, I get something like this: ['Python', 
'best', 'ever', 'is', 'language', 'programming', 'the'] with brackets. 
Is there a way to use format() to remove the brackets before the list is 
printed?

Thanks for the help!

That is because you are printing a list and not a string. ['Python', 'best', 'ever', 'is', 'language', 'programming', 'the'] is a list where the first element is 'Python', the second element is 'best', and etc. To print a string instead of a list you can use a string's join function to convert a list into a string.

>>> ' '.join( itemlist )
'Python is the best programming language'
>>> ' '.join( sorted( itemlist ) )
'Python best is language programming the'
