Python print() built-in function

From the Python 3 documentation

Print objects to the text stream file, separated by sep and followed by end. sep, end, file, and flush, if present, must be given as keyword arguments.

The print() function writes the value of the argument(s) it is given. […] it handles multiple arguments, floating point-quantities, and strings. Strings are printed without quotes, and a space is inserted between items, so you can format things nicely:

>>> print('Hello world!')
# Hello world!

>>> a = 1
>>> print('Hello world!', a)
# Hello world! 1

The end keyword

The keyword argument end can be used to avoid the newline after the output, or end the output with a different string:

phrase = ['printed', 'with', 'a', 'dash', 'in', 'between']
>>> for word in phrase:
...     print(word, end='-')
# printed-with-a-dash-in-between-

The sep keyword

The keyword sep specify how to separate the objects, if there is more than one:

print('cats', 'dogs', 'mice', sep=',')
# cats,dogs,mice
