Import statement

The custom module can be introduced using the import statement. The operation step is to import the module first, and then call the functions contained in the module. You can put the custom module into the current directory to facilitate path search of the interpreter. The following is an example of importing a custom hello.py module and calling the World function:

#! / usr/bin/python

#-*-coding: UTF-8-*-

# Import module

Import hello

# now you can call the functions contained in the module

Support.print_func ("World")

The output is as follows:

Hello World!

From can also be used for the above examples. Import is implemented by importing the specified part from a module into the current namespace. The above functions can be written as follows:

#! / usr/bin/python

#-*-coding: UTF-8-*-

From hello import World

#! / usr/bin/python

#-*-coding: UTF-8-*-

From hello import *

Also note that when you import a module, the Python interpreter searches the location of the module in the following order:

1. Current directory

two。 If it is not in the current directory, Python searches each directory under the shell variable PYTHONPATH

3. If neither is found, Python looks at the default path.
