Write text without new lines
The
parameter end controls what is printed after the text to be printed. Its default is the
new line.
The following example assigns a whitespace to end so that multiple invocations of print write on the same line.
Alternatively, text without new lines can also be written with
sys.stdout.write().
print('one', end = ' ')
print('two', end = ' ')
print('three')
import sys
sys.stdout.write('foo ' )
sys.stdout.write('bar ' )
sys.stdout.write('baz\n')
Print a list
If a
list is passed to
print(), the list is printed with the square brackets (
[ elem, elem… ]).
In order to print the individual elements of the list, the list must be prepended with a * (unpacking operator):
lst = [ 'foo', 'bar', 'baz' ]
print(lst)
#
# ['foo', 'bar', 'baz']
print(*lst)
#
# foo bar baz
Print elements with a user defined separator
The
sep parameter allows to define the separator with which the elements are printed.
print('foo', 'bar', 'baz', sep=', ')
#
# foo, bar, baz(
lst = [ 'one', 'two', 'three' ]
print(*lst, sep=' - ')
#
# one - two - three
