Because Popen is not a module. Why do you expect it to be a module? py> type(int) <class 'type'> py> type(float) <class 'type'> py> type(str) <class 'type'> py> class X(object): ... pass ... py> type(X) <class 'type'> >>>> type(subprocess.Popen) > <class 'type'> Popen is a class, also known as a "type". >>>> import os >>>> type(os.path) > <class 'module'> os.path is a module, just like os. Inside the os module, you will find code that looks something like this: if the operating system is Windows: import ntpath as path elif the operating system is Unix: import posixpath as path else: import genericpath as path So os.path is a module. -- Steve “Cheer up,” they said, “things could be worse.” So I cheered up, and sure enough, things got worse. -- https://mail.python.org/mailman/listinfo/python-list
