To speed up loading modules, Python caches the compiled version of each module in the __pycache__ directory under the name module. The network can be created by calling functions from one file to another. So, a Python function is a group of codes that allows us to write blocks of code that perform specific tasks. Import in Python is analogous to #include header_file in C/C++. I am trying to call a function saved in another file to run in this file's code. anotherfile.py is in the same directory as current code.

Another option is to have a third module that loads eeg_data, that both EEG and Digital_Filter can import. But, when I put all the code in one file and then run func start, everything works fine. If we look at the forms module, we can see that it contains another module named forms, one named models and other modules as well, omitted in the picture. 6.1.3. .

Python Dictionary Methods Python Tuple Methods Python Set Methods Python File Methods Python Keywords Python Exceptions Python Glossary Module Reference . Consider modules as, just another piece of python code, saved somewhere within the python package and you can reuse the code from the module files in any other (or your) python code file. Approach: Create a Python file containing the required functions. . Now, I would like to import functions in another file by using "import functions". For example, the same directory has two Python file baseFile.py and callerFile.py having their functions. Calling a Function. Note that although the file name must contain a .py extension, .py is not used as part of the filename during import.
