filename: the filename tobe read strip_newline: strip the last space/newline
2.1.2 return lines readed from file
2.1.3 Example:

2.5 DEMO

3 Using progress
3.1 print_progress
print_progress(msg, current, max, max_width=60)
Demo
example/demo_files.py
#!/usr/bin/env python3 #demo_progress.py import time from ezutils.progress import print_progress if __name__ == '__main__': max = 100 for i in range(max + 1): print_progress("MSG:ABC(%d)" % i, i, max) time.sleep(0.01)
TODO:
pillow utils
add roundrect for pillow see and ANTIALIAS circle_corner
