Python date wild card

AndrewL

Hi I have the following code that works correctly. However, every once in a while there is a file name that has an "06" instead of an "05" and it breaks the script. Is there a way I can use a wild card for that digit?

        fileName <SPAN class="operator token">=</SPAN> os<SPAN class="punctuation token">.</SPAN>path<SPAN class="punctuation token">.</SPAN>split<SPAN class="punctuation token">(</SPAN>fullFileName<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">[</SPAN><SPAN class="operator token">-</SPAN><SPAN class="number token">1</SPAN><SPAN class="punctuation token">]</SPAN>
        fileNameShort <SPAN class="operator token">=</SPAN> fileName<SPAN class="punctuation token">[</SPAN><SPAN class="punctuation token">:</SPAN><SPAN class="operator token">-</SPAN><SPAN class="number token">13</SPAN><SPAN class="punctuation token">]</SPAN>
        fileDateTime <SPAN class="operator token">=</SPAN> dt<SPAN class="punctuation token">.</SPAN>strptime<SPAN class="punctuation token">(</SPAN>fileName<SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"%m%d%Y_%H05shapefile.zip"</SPAN><SPAN class="punctuation token">)</SPAN>‍‍‍‍‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

Sure. We use the Weather Climate Toolkit (a program from NOAA) to automatically download the zip files every hour. They are named after the date/time they are downloaded. However, recently it sometimes takes more than one minute to download a file which causes it to have an "06" instead of "05." Thanks.

How you are applying the date format for datetime.strptime is unusual, even if it is working. Typically, the date/time formatting only includes date/time components and not additional text.

It seems you are working with a group of files that have consistent naming, can you provide an example of a file name and what you are trying to get because there might be a better overall approach.
