import time
import sys
toolbar_width = 40
# setup toolbar
sys.stdout.write("[%s]" % (" " * toolbar_width))
sys.stdout.flush()
sys.stdout.write("\b" * (toolbar_width+1)) # return to start of line, after '['
for i in xrange(toolbar_width):
time.sleep(0.1) # do real work here
# update the bar
sys.stdout.write("-")
sys.stdout.flush()
sys.stdout.write("]\n") # this ends the progress bar
Example 2:
The code below can be adapted to fit your needs by customizing: bar progress symbol '#', bar size, text prefix etc.
import sys
def progressbar(it, prefix="", size=60, file=sys.stdout):
count = len(it)
def show(j):
x = int(size*j/count)
file.write("%s[%s%s] %i/%i\r" % (prefix, "#"*x, "."*(size-x), j, count))
file.flush()
show(0)
for i, item in enumerate(it):
yield item
show(i+1)
file.write("\n")
file.flush()
Usage:
import time
for i in progressbar(range(15), "Computing: ", 40):
time.sleep(0.1) # any calculation you need
from progress.bar import Bar
bar = Bar('Processing', max=20)
for i in range(20):
# Do some work
bar.next()
bar.finish()
The result will be a bar like the following:
Processing |############# | 42/100
Example 3:
Try PyProg. PyProg is an open-source library for Python to create super customizable progress indicators & bars.It is currently at version 1.0.2; it is hosted on Github and available on PyPI (Links down below). It is compatible with Python 3 & 2 and it can also be used with Qt Console.
It is really easy to use. The following code:
import pyprog
from time import sleep
# Create Object
prog = pyprog.ProgressBar(" ", "", 34)
# Update Progress Bar
prog.update()
for i in range(34):
# Do something
sleep(0.1)
# Set current status
prog.set_stat(i + 1)
# Update Progress Bar again
prog.update()
# Make the Progress Bar final
prog.end()
Output:
Initial State:
Progress: 0% --------------------------------------------------
When half done:
Progress: 50% #########################-------------------------
Final State:
Progress: 100% ##################################################
You can easily install it with: pip install pyprog.
