The **`os.geteuid()`** **method** is used to extract the effective user ID of the current process. The inverse method of this function is **`seteuid()`**, which is used to set the effective user ID. These methods are commonly found on #key# UNIX: A multi-user operating system #key# based systems.
> Note: The **`OS`** **module** in Python is used to deal with operating system commands. 



The effective user ID determines the level of access that the current process has. When we give access as root to a non-privileged user, 
then an effective user ID assigned instead of a user ID.

# 
## Syntax
---
```python
os.geteuid()
```
---

## Parameters
`N/A`: It does not take any argument value(s).
## Return value
This method returns an effective user ID as an integer type. 

## Code example
Now, let's see an example of this method.

# Program to show working of geteuid() method
# importing mobules
import os
import random
# generating random number between 10-100
euid = random.randint(10,100)
# Assigning effective user id to current thread
os.seteuid(euid)
# Extracting id to test this method
euid= os.geteuid()
# printing euid on console
print(euid)

## Code explanation
* **Line 6**: We generate a random number between 10 and 100, to use an an effective user ID.
* **Line 8**: We assign an effective user ID to the current process.
* **Line 10**: We get the effective user ID of that process, by using the `os.geteuid()` method.
* **Line 12**: We print the #key# euid: Effective user ID #key# to the console.

What is os.geteuid() in Unix using Python?

os.geteuid() retrieves the effective user ID of the current process in Unix-based systems using Python.
