Why are global variables bad python?

The reason global variables are bad is that they enable functions to have hidden (non-obvious, surprising, hard to detect, hard to diagnose) side effects, leading to an increase in complexity, potentially leading to Spaghetti code.

How do you define a global function?

Global keyword is a keyword that allows a user to modify a variable outside of the current scope. It is used to create global variables from a non-global scope i.e inside a function. Global keyword is used inside a function only when we want to do assignments or when we want to change a variable.

What's the difference between VAR and let?

The main difference between let and var is that scope of a variable defined with let is limited to the block in which it is declared while variable declared with var has the global scope. So we can say that var is rather a keyword which defines a variable globally regardless of block scope.

What are the rules for local and global variables in Python?

Rules for local and global variables in python?

• In python, the variables referenced inside a function are global.
• When a variable is assigned new value anywhere in the body of a function then it is assumed as local.
• In a function, if a variable ever assigned new value then the variable is implicitly local and explicitly it should be declared as global.

Should you use global variables in Python?

While in many or most other programming languages variables are treated as global if not declared otherwise, Python deals with variables the other way around. They are local, if not otherwise declared. The driving reason behind this approach is that global variables are generally bad practice and should be avoided.
