python-3.7

问题 Currently we are working on an application which is trying to calculate the travel time of a route from a to b, using the 2.db.transport.rest API. Unfortunatly we are receiving timestamps with a timezone offset from that API, such as +01:00 . What we need is a timezone offset without the : , so +0100 . The following example gives an error on Linux, using Python 3.6.7: from datetime import datetime datetimestring = "2019-01-19T15:13:00.000+01:00" datetime.strptime(datetimestring, '%Y-%m-%dT%H:

问题 On Ubuntu 18.04 with python 3.7.3, I'm attempting to import pandas but this fails because it can't find _lzma . I've verified that _lzma is installed with dpkg: /usr/lib/python3.7/lib-dynload/_lzma.cpython-37m-x86_64-linux-gnu.so. Oddly, _lzma is not a dependency of pandas (as specified by pip3). 回答1: I was running into this exact same issue today! I was able to fix it though. Pandas just put out a new version 0.25.0 on July 18th and changing the version back to 0.24.2 fixed this issue for me
