What you want to do is to take your Python file, and use it as a module or a library. Show
There's no way to make those four functions automatically available, no matter what, 100% percent of the time, but you can do something very close. For example, at the top of your file, you imported You want to do the same thing -- save those 4 functions into a file, and import them whenever you want them. For example, if you copy and paste those four functions into a file named If you want to make your module available system-wide, you have to save it somewhere on the PYTHONPATH. Usually, saving it to
In Python, you can save the definitions of functions in a file called a module. It is possible to import module definitions into your program file. We can save our Python functions in their own file, which is a module, then the module is imported to the main program. To have the module available within the current program, an import statement is used to transfer it to the running program. When separate files are used to store functions, the program’s code details are hidden and a higher level of logic for the program code is attained. Storing your functions in different files has the following advantages:
We can import these modules in different ways, such as:
PrerequisitesIn order to follow through with this article, a clear understanding of Python modules is required. Importing an entire moduleThe first step is to create a
module, which is a file that has an ending of Below is a module with the function
We can have another separate file This is the file,
A command from the line Abstraction of the data from the user takes place such that one does not understand what happens in the background. All one needs to know is that any function that is defined in We call a function from an imported module by entering the module name imported and the function name separated by a dot. The result of the program will be similar whether a module is imported or not. The output should be as follows: Making a 11-inch bread with the following garnish: -basil Making a 14-inch bread with the following garnish: -garlic flakes -oregano -rolled oat flakes Syntax of importing an entire module:
All functions within the module name are imported without an exception. Importing specific functionYou can as also import just a specific function from a module. The syntax when importing a specific function:
Importing various specific functions from a module is made possible by separating the function’s name with a comma:
From the file
This is a better option when you are not required to import an entire module and all the functions won’t be put into use. Giving a function an alias using ‘as’An alias is used mainly when the function name is too long or when the function name is similar to another name in the program. If in any of the instances occur, we use an alias that is an alternate name similar to that of the function. The general syntax of using an alias is as shown below:
From the function
The import statement renames the function name to the alias. In this case, the function Anytime we need to call the function The alias avoids any confusion with another function that might be written in the program as Giving a module an alias using ‘as’An alias of a module can be given based on the module name. Providing an alias for a module makes it easier to call the module’s function. The syntax when giving a module an alias:
We can call
Giving an alias to a module does not change the function names, instead they retain their original names. Using the alias name for the module is not only concise but also enables you to concentrate on the informative names of the function, thus, redirecting your attention from the name of the module. These function names will tell you what the function does, to enable the readability of your code rather than using the full name of the module. Importing all functions in a moduleTo import all the functions in a module we use the asterisk The syntax of importing all functions in a module is as follows:
Functions can be called without using the dot notation. In instances where we are working with large modules that you did not write, it is not appropriate to use this approach.
If several functions are saved under the same name, the code will not import the functions separately. Instead, it will overwrite all the functions. Errors and the unexpected output may result due to the matching of the function names and other existing names in the function. ConclusionIn the tutorial above we have been able to look at how easy and important it is to import functions and modules. We have looked at:
