timelength 1.1.2

A Python package to parse human readable lengths of time.

timelength

Inspired by durations by oleiade.

A Python package to parse human readable lengths of time, including long form such as 1 day, 5 hours, and 30 seconds, short form such as 1d5h30s, and a mix thereof such as 1 day 5h 30s. Includes default relaxed parsing and optional strict parsing. Supports custom abbreviations, scale factors, and more.

Installation

timelength can be installed via pip:

$ pip install timelength

Usage

To parse a length of time, instantiate a TimeLength object with the string of text to parse. The text should include pairs of Values and Scales.

• A Value is a number.
• A Scale is a length of time from Milliseconds to Centuries, including short form and various other potential abbreviations associated with each scale.
• Acceptable separators of multiple Values and Scales are commas, the word "and", normal spaces, and tab characters.

Scale Reference

• Millisecond: ms, millisecond, milliseconds
• Second: s, second, seconds
• Minute:m, minute, minutes
• Hour: h, hour, hours
• Day: d, day, days
• Week: w, week, weeks
• Month: M, month, months
• Year: y, year, years
• Decade: D, decade, decades
• Century: c, century, centuries
• Various other abbreviations viewable with timelength.Day().terms etc

Usage Example

from timelength import TimeLength

time_string = "5.5min, and 10 seconds"

parsed_length = TimeLength(time_string)
parsed_length.total_seconds
# >>> 340.0
parsed_length.to_hours()
# >>> 0.09
parsed_length.to_hours(max_precision = 5)
# >>> 0.09444
parsed_length.strict
# >>> False
parsed_length.passed_value
# >>> 5.5min, and 10 seconds
parsed_length.parsed_value.valid
# >>> [(5.5, 'minutes'), (10.0, 'seconds')]
parsed_length.parsed_value.hours
# >>> None
parsed_length.parsed_value.minutes
# >>> 5.5
parsed_length.parsed_value.seconds
# >>> 10

time_string = "5 ish minutes and uhhh, 7 seconds?"

parsed_length = TimeLength(time_string)
parsed_length.to_seconds()
# >>> 307.0
parsed_length = TimeLength(time_string, strict = True)
# >>> InvalidValue: ... contains invalid values: ['ish', 'uhhh', '?']

from timelength import TimeLength, Minute
from copy import deepcopy

time_string = "5.5MiNuTeS, and 10 seconds"
cust_min = deepcopy(Minute())
cust_min.terms.append("MiNuTeS")

parsed_length = TimeLength(time_string, custom_minute = cust_min)
parsed_length.total_seconds
# >>> 340.0
parsed_length.passed_value
# >>> 5.5MiNuTeS, and 10 seconds
parsed_length.parsed_value.valid
# >>> [(5.5, 'minutes'), (10.0, 'seconds')]
