Ways to find file paths using the Glob module in Python

This article mainly introduces in Python uses the Glob module to look for the file path the method, uses the module the Iglob method to realize is very simple, needs the friend to be possible to refer to under

The Glob module is one of the simplest modules with very little content. Use it to find a file path name that matches a specific rule. It's about the same as using a file search under Windows.

Glob.iglob

Gets a calendar object that can be used to get a matching file pathname. The difference from Glob.glob () is that Glob.glob gets all the matching paths at the same time, and Glob.iglob gets only one matching path at a time. It's kind of like. NET, the dataset and DataReader used in the Operation database. The following is a simple example:

?

Import glob #父目录中的. py file F = Glob.iglob (R ' ... /*.py ') Print F #<generator object Iglob at 0x00b9ff80> for py in f:print py

It ' s so easy, is ' t it?
