How can I print multiple things on the same line, one at a time?

Python 3 Solution

The print() function accepts an end parameter which defaults to \n (new line). Setting it to an empty string prevents it from issuing a new line at the end of the line.

def install_xxx():
    print("Installing XXX...      ", end="", flush=True)

install_xxx()
print("[DONE]")

Python 2 Solution

Putting a comma on the end of the print() line prevents print() from issuing a new line (you should note that there will be an extra space at the end of the output).

def install_xxx():
   print "Installing XXX...      ",

install_xxx()
print "[DONE]"
