How to print some information on the same line without introducing a new line

Q1 Q2.

Instead, my question is as follows:

I expect to see the following effect,

>> You have finished 10% 

where the 10 keep increasing in the same time. I know how to do this in C++ but cannot find a good solution in python.

Answer 1

import sys, time  for i in xrange(0, 101, 10):   print '\r>> You have finished %d%%' % i,   sys.stdout.flush()   time.sleep(2) print 

The \r is the carriage return. You need the comma at the end of the print statement to avoid automatic newline. Finally sys.stdout.flush() is needed to flush the buffer out to stdout.

For Python 3, you can use:

print("\r>> You have finished {}%".format(i), end='') 

Answer 2

Python 3

You can use keyword arguments to print:

print('string', end='\r', flush=True)

• end='\r' replaces the default end-of-line behavior with '\r'
• flush=True flushes the buffer, making the printed text appear immediately.

Python 2

In 2.6+ you can use from __future__ import print_function at the start of the script to enable Python 3 behavior. Or use the old way:

Python's print puts a newline after each command, unless you suppress it with a trailing comma. So, the print command is:

print 'You have finished {0}%\r'.format(percentage), 

Note the comma at the end.

Unfortunately, Python only sends the output to the terminal after a complete line. The above is not a complete line, so you need to flush it manually:

import sys sys.stdout.flush()
