statements must be separated by newlines or semicolons

In programming languages, statements must be separated by either newlines or semicolons, depending on the specific language’s syntax rules.

Some languages, like Python, use newlines to separate statements, and do not require semicolons at the end of each statement. Other languages, like JavaScript and C++, allow either newlines or semicolons to separate statements.

Regardless of the specific syntax rules, it is important to use consistent formatting and adhere to best practices to ensure code readability and maintainability.

Python global variable

In Python, a global variable is a variable that is defined outside any function and can be accessed from anywhere in the code. It can be modified and accessed by any function in the module.

To define a global variable in Python, you simply need to define it outside any function:

makefile

x = 10  # global variable

In the example above, x is a global variable, and it can be accessed and modified from anywhere in the module. For example:

python

def my_function():

    global x  # to access the global variable inside a function

    x = 20   # modify the value of the global variable

my_function() # call the function to modify the value of the global variable print(x) # Output: 20

In the function above, we declared x as a global variable using the global keyword. This allows us to modify the value of the global variable inside the function. When the function is called, the value of x is changed from 10 to 20.

Note that using global variables can make your code harder to debug and maintain, as it can introduce unintended side-effects. It is generally recommended to use local variables wherever possible, and pass data between functions explicitly through arguments and return values.
