Today, I would like to share with you what are the relevant knowledge points about the matching method of Python file names, which are detailed in content and clear in logic. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article.

Wildcard character

Asterisk (*)

Needless to say, let's use wildcards to match file names, as shown in the following example:

Import globfor name in sorted (glob.glob ('text/*')): print (name) question mark (? )

Question mark (? ) is used to match words, for example, we choose the picture file that starts with 1 above. Examples are as follows:

Import globfor name in glob.glob ('text/1?.png'): print (name) interval matching ([0-9] [Amurz] [Amurz])

From the above two matches, we can see that the matching rules of the glob library are somewhat similar to regular expressions. Since it can match one or more obscure characters, then surely it can also match interval characters.

Examples are as follows:

Import globfor name in glob.glob ('text/ 15 [a-z]. *'): print (name) escapes metacharacters

Of course, the above file names are regular file names, made up of letters and numbers. However, some people are weird and may include special characters in the file name, such as the matching character "? * [" above. What are we going to do? Is it escaped with a backslash?

In fact, we have a simpler way to operate directly using the escape () function. Examples are as follows:

Import globescape_str='?* [] 'for char in escape_str: pattern =' text/*' + glob.escape (char) + '.png' for name in glob.glob (pattern): print (name) is all the contents of this article entitled "what are the matching methods for Python filenames?"
