In this article we will show you the solution of how to find python path, in Python, there are various techniques to find paths in python. We use sys. executable, sys. prefix, os.environ.get() to get the path in Python. sys. executable gives the python path of the executable python code.

For example, if we use sys.executable method and run the code using this method with any Python ide we get the Python path.

Here is the sample format of the python path of using sys.executable“C:\Users\LENOVO\Desktop\pythonproject\findingpath\venv\Scripts\python.exe” .

findingpath indicates the file name where we write the code. When we use sys. prefix, it gives the python path where the python is installed in the virtual environment for example when we run this code in any python ide it gives“C:\Users\LENOVO\Desktop\pythonproject\findingpath\venv”.

os. environ.get() method gives the Python path that is located in an environment variable.

If we use Windows we can easily search environment variables to check the python path.

Environment variables contain user environment variables and system environment variables.

The user environment variable indicates that the variable can access and set only users.

The system environment variable indicates that the variable can be set and accessed through the system or we can say it is available to all users.

Step By Step Guide On How To Find Python Path :-

1. Using sys.executable to find python path

import sys
my_path=sys.executable
print(my_path) #C:\Users\LENOVO\Desktop\pythonproject\findingpath\venv\Scripts\python.exe
  1. We first import sys.
  2. We can use sys. executable to get the python path and assign in a variable my_path that prints the path. findingpath is our sample file where we write our python code.

2. Using sys.prefix to get the python path

import sys
my_path=sys.prefix
print(my_path) #C:\Users\LENOVO\Desktop\pythonproject\findingpath\venv
  1. We first import sys.
  2. We can use sys. prefix it gives the python path where the python is installed in the virtual environment.

3. Using os.environ.get() to get the python path

import os
my_path=os.environ.get("PYTHONPATH")
print(my_path) #C:\Users\LENOVO\Desktop\pythonproject\findingpath
  1. Firstly we import os, which is the built-in module.
  2. We use os.environ.get() to give the value of the PYTHONPATH variable and assign to a variable my_path. 
import os
b = os.path
correct_path= "C:\\Users\\LENOVO\\Desktop\\pythonproject\\findingpath\\venv\\Scripts\\python.exe"
if b.exists(correct_path):
    print("path is found")
else:
    print("path is not found")
  1. In this code, we also check if my path exists or not.
  2. Firstly we import os and use os. path to get the Python path and assign it in a variable b it shows the path in terms of the module name, location, etc.
  3. We assign a correct_path of python and check if the python path that is generated using os. path exists in correct_path then print “path is found” and else it shows “path is not found”.

Conclusion :-

In conclusion, we successfully learned how to find Python paths in Python.

We learned various methods such as sys. executable, sys. prefix, os.environ.get(). We learned sys. executable gives the python path of the executable python code.

sys. prefix, it gives the python path where the Python is installed in the virtual environment. os.environ.get() method gives the Python path that is located in the environment variable.

Based on your suitability you can choose any one of the mentioned methods that suits you.

I hope this article on how to find python path helps you and the steps and method mentioned above are easy to follow and implement.
