Scope of Variable in User Defined Function
Introduction:
In programming, the scope of a variable refers to the region in the code where the variable is recognized and can be accessed. It determines the accessibility and lifetime of a variable. The scope of a variable depends on where it is declared.
Variable Scope in User Defined Function:
The scope of a variable declared in a user-defined function is limited to the block of code within the function, denoted by the curly braces {}.
Explanation:
When a variable is declared inside a user-defined function, its scope is restricted to that function only. This means that the variable can only be accessed and used within the block of code defined by the function.
Example:
Let's consider the following example to understand the scope of a variable in a user-defined function:
```python
def my_function():
x = 5
print(x)
my_function()
print(x) # This will result in an error
```
In the example above, a variable named 'x' is declared and assigned a value of 5 inside the function 'my_function()'. The variable 'x' can be accessed and used within the function. However, if we try to access the variable 'x' outside the function, it will result in an error because the variable is not defined in the global scope.
Conclusion:
The scope of a variable declared in a user-defined function is limited to the block of code within the function. It cannot be accessed or used outside the function. This helps in encapsulating variables within functions and prevents naming conflicts with other variables in the program.
