Etc provides some generators to give an estimated time left, when doing big for loops in python.
Iterate over a range 10, returning progress and estimated time remaining every iteration:
for i, pi in etc.range(10):
if pi:
print("progress at %g"%pi.progress)
print("%g seconds elapsed"%pi.elapsed_time)
print("%g seconds remaining"%pi.time_remaining())
print("")

Iterate over a range 100,000 returning progress info every 10 seconds:
for i, pi in etc.range(100000, info_frequency=10):
if pi:
print("progress at %g"%pi.progress)
print("%g seconds elapsed"%pi.elapsed_time)
print("%g seconds remaining"%pi.time_remaining())
print("")

etc.range(n, info_frequency=0):
Simple range from 0 to n-1 in steps of 1. More complex ranges
can be done using sequence_timer. Returns a tuple (i, progress_info),
where progress_info can be either a ProgressInfo object, or None.
info_frequency is the time in seconds that pass between valid progress_info
objects getting returned from the generator.
etc.sequence_timer(sequence, info_frequency=0):
Iterate over a sequence, such as a list. Returns a tuple (i, progress_info),
where progress_info can be either a ProgressInfo object, or None.
info_frequency is the time in seconds that pass between valid progress_info
objects getting returned from the generator.
etc.file_timer(in_file, info_frequency=0):
Iterate over the lines in a file. Returns a tuple (i, progress_info),
where progress_info can be either a ProgressInfo object, or None.
info_frequency is the time in seconds that pass between valid progress_info
objects getting returned from the generator.
ProgressInfo
Information on the current progress, elapsed time, and time remaining of the current generator.
ProgressInfo.progress
Current progress from 0 to 1 of the generator.
ProgressInfo.elapsed_time
Time in seconds the generator has been running.
ProgressInfo.time_remaining()
Estimated time remaining of the loop.
