- Later, call the function using: function(a, b) Note that file is one of Python's core modules, so I suggest you change the filename of file.py to something else. Note that if you're trying to import functions from a.py to a file called b.py, you will need to make sure that a.py and b.py are in the same directory.

You can call the function from a different directory as well, in case you cannot or do not want to have the function in the same directory you are working. You can do this in two ways (perhaps there are more alternatives, but these are the ones that have worked for me).
Jul 20, 2011 · from my_module import function1, function2, function3, function4, function5, function6, function7. See "Explicit is better than implicit." in import this. If you just want a shorter name than my_module.function1, there is always import my_module as mod.
Note: When using a function from a module, use the syntax: module_name.function_name. Variables in Module The module can contain functions, as already described, but also variables of all types (arrays, dictionaries, objects etc):

We can import the definitions inside a module to another module or the interactive interpreter in Python. We use the import keyword to do this. To import our previously defined module example, we type the following in the Python prompt. This does not import the names of the functions defined in example directly in the current symbol table. It only ...
The Python standard library contains well over 200modules. We can import a module according to our needs. Suppose we want to get the value of pi, first we import the math module and use math.pi. For example, Output
In Python, we can also import a module by renaming it. For example, Here, We have renamed the math module as m. This can save us typing time in some cases. Note that the name math is not recognized in our scope. Hence, math.pi is invalid, and m.piis the correct implementation.
We can import specific names from a module without importing the module as a whole. For example, Here, we imported only the pi attribute from the mathmodule.
In Python, we can import all names(definitions) from a module using the following construct: Here, we have imported all the definitions from the math module. This includes all names visible in our scope except those beginning with an underscore(private definitions). Importing everything with the asterisk (*) symbol is not a good programming practic...
In Python, we can use the dir()function to list all the function names in a module. For example, earlier we have defined a function add() in the module example. We can use dir in examplemodule in the following way: Here, we can see a sorted list of names (along with add). All other names that begin with an underscore are default Python attributes a...
Aug 2, 2022 · Let’s see how to use functions defined in any module. First, we need to use the import statement to import a specific function from a module. Next, we can call that function by its name.
Inside the file myfuctions.py, two functions are defined using the code below. # myfunctions.py def plustwo (n): out = n + 2 return out def falldist (t,g=9.81): d = 0.5 * g * t**2 return d. This file, myfunctions.py can be imported into another script (another .py file), or Jupyter Notebook.
May 12, 2023 · You can access functions and constants defined in the module using the syntax <module_name>.<function_name> or <module_name>.<constant_name>.
