How to print list by using format function

Question

I transfer form JAVA and pretty new in python.I knew python is a convenience language. Then I consider if or not a way I could use in print(''.format()) function to print a list, which I insert couple of word in between value.

I have already tried print(''.format(for i in list)) as simple example showed below:

movies.append(1)
movies.append('The Shawshank Redemption')
movies.append('5 star')
movies.append('whatever')
movies.append('www.google.com')
print('''
    The NO.{} Movie is :{}
    Rating:{}
    Quote:{}
    Link:{}
    '''.formate(for i in movie)

of course, it shows error invalid syntax at last statement.

A list is not the ideal data structure here, you would have better luck with a dictionary. movies = [{'title': 'The Shawshank Redemption', 'rating': '5 star', 'quote':'whatever', 'link': 'www.google.com'}] You aren't using .format() correctly. It is for formating a single string with a list of input arguments. You could use it in a loop, but not as a loop. — campellcl

The syntax error is that you are missing a closing parenthesis ) (also format not formate) — Tim

@juanpa.arrivillaga Good call, forgot about the list unpacking operator. That would work well here. — campellcl

for i in movies is a for statement, so it expects to have a block of code.

What you want is to get every item for item in movies, and then pass each item to the function, so you should do this instead

print('''
    The NO.{} Movie is :{}
    Rating:{}
    Quote:{}
    Link:{}
    '''.format(*(i for i in movie)) # '*' unpacks the generator, so instead of passing a whole object to the function, you pass every object in the generator as an argument

Note that you can actually pass the unpacked list to format like so

print('''
    The NO.{} Movie is :{}
    Rating:{}
    Quote:{}
    Link:{}
    '''.format(*movies) # '*' unpacks the generator, so instead of passing a whole object to the function, you pass every object in the generator as an argument

*movies unpack argument lists

movies = []
movies.append(1)
movies.append('The Shawshank Redemption')
movies.append('5 star')
movies.append('whatever')
movies.append('www.google.com')
print('The NO.{}\nMovie is :{}\nRating:{}\nQuote:{}\nLink:{} '.format(*movies))

Output is

The NO.1
Movie is :The Shawshank Redemption
Rating:5 star
Quote:whatever
Link:www.google.com
