[python] How can I suppress the newline after a print statement?

The question asks: "How can it be done in Python 3?"

Use this construct with Python 3.x:

for item in [1,2,3,4]:
    print(item, " ", end="")

This will generate:

1  2  3  4

See this Python doc for more information:

Old: print x,           # Trailing comma suppresses newline
New: print(x, end=" ")  # Appends a space instead of a newline

Aside:

in addition, the print() function also offers the sep parameter that lets one specify how individual items to be printed should be separated. E.g.,

In [21]: print('this','is', 'a', 'test')  # default single space between items
this is a test

In [22]: print('this','is', 'a', 'test', sep="") # no spaces between items
thisisatest

In [22]: print('this','is', 'a', 'test', sep="--*--") # user specified separation
this--*--is--*--a--*--test
