tram-age's Introduction

Compute age of trams in Russian cities

The most of systems of public transportation in Russia uses ancient wagons. List of passenger vehicles by particular city is available at URL like https://transphoto.org/list.php?serv=0&cid=54&t=1, list of Russian cities available at https://transphoto.org/country/1/

This program fetches data for specified city and type of transportation and then make some statistical computation.

Preparing

make prepare
. env/bin/activate

sudo apt install pip3-venv
python3 -m venv env
. env/bin/activate
pip install -r requirements.txt

Usage

compute.py [-h] [-c CITY] [-t TYPE] [-l LANGUAGE]

Optional arguments

-h, --help — show help message and exit
-c CITY, --city CITY — number or name (default city is Moscow)
-t TYPE, --type TYPE — transportation type (digit 1 to 9 or name, default value is tram)
-l CODE, --language CODE — ISO 639-1 language code (default is ru for Russian)
-o FILE, --output FILE — output frequency table to file. Format detected by filename without case sensitivity.

File formats

CSV — Comma Separated Values — file.csv
HTML — Hypertext Markup Language — file.htm, file.html
JSON — JavaScript Notation Object — file.json, file.js
Microsoft Excel — file.xls (legacy), file.xlsx

Examples

It's possible to use digital IDs

$ python compute.py --city 229 --type 2
Миасс, троллейбус

tram-age's Issues

Wrong year parsing

Different languages have different date formats: mm.YYYY for Russian but YYYY-mm for Lithuanian:

$ python3 compute.py -l lt -c zlatoust
Zlatoust, tramvajus
-------------------
0-04       1 #
1978       1 #
1981       1 #
1985       2 ##
1986       1 #
1988       1 #
1992       2 ##
1995       4 ####
1996       2 ##
1997       2 ##
2-08       1 #
2000       2 ##
2002       1 #
2004       1 #
2008       1 #
2009       3 ###
3-10       1 #
5-04       1 #
5-06       1 #
7-12       1 #
8-04       1 #
------------
Total     31

So year should be extracted via regular expression \d{4} instead of four last characters.
