GLOBAL & LOCAL VARIABLE - PYTHON PROGRAMMING

GLOBAL VARIABLE : A variable declared outside of the function or in global scope is known as global variable. This means, global variable can be accessed inside or outside of the function.
LOCAL VARIABLE : A local variable is a variable which is either a variable declared within the function or is an argument passed to a function.

Hello, why a=40 is local if it’s declared outside the function?

You missed two things bro 1) we can change the value of global variable from the function using global keyword 2)we can call the global variable from function when both having same name by using globals()

Sir as u said in structure of a c program.we have to write user defined function after the completion of main function so,here in this concept u discussed like main function will come after the user defined function....so..here I have doubt like both are same or not......?

Hi First we have to write user-defined function and then we have to write function call.

When global and local variable with same name, how can I access global variable from local scope area

[@AjayJain-ef2mz]

hey i think i can solve your problem. #creating a global variable a = 10 def prnt(): #creating a local variable a=20 #Now we want to access 'a' with value 10 x = globals()['a'] print(x) #this will print 10 globals()['a'] = 20 #value of global variable a has been changed to 20

[@digitalduniyag.a2748]

Sir you are great .. But sir pleae upload one video regarding main and user define function ... How can we diffrentiate between them. .. And how would we use both in one progam

[@muruga30]

Example: #1 def add(): #2 a=10 #3 b=20 #4 print(a+b) #5 add() #6 print("End") A user defined function ends with : ,that is function header. After colon (:) the statements are pressed with space that is Indentation that is function body. Here the line #1,#2,#3,#4 are user defined function. #5 and #6 doesn't have any indentations. That is main program or top level statements

[@_weebxarmy_2009]

Great explanation thank you so much sir

[@shinimannan]

Sir, great session, Thanks. Have a very basic question. Have not understood what is the use of the line -> def display ( ): in the user defined function and the line -> display( ) in the main function.

[@chennupatiharika9863]

Def display: definition section..... I.e fun definition Display:main function section I.e fun call

a=10 # global def disp(): print(a) def show(): a=20 # local print(a) # o/p =20 =>here I want to access global var a. Is possible in python.

[@sathishyerraguntla8099]

yes it is possible

[@Mrbeansololover]

a=10 #global def disp(): print(a) def show() a=20 a= globals ()['a'] print(a) #with the use globals () we can get the global variable instead of local variable

Here it will print global variable

[@d.sairamdronamraju1555]

Thank you sir

[@hanu-tw3js]

Sir after calling function we some a=10 a is global or local variable because it is out side the function???

[@rajeshkumar-rg9id]

Hi sir,in user defined function instead print i think we need to write return?

[@beetlenut6980]

Not necessarily, In case you want the program to return some value you should not write print For example: def addNum(num1, num2): print(num1 + num2) addNum(2, 3) Output: 5 What happened here is the function just prints something to screen for this example it's 5, Now if you want this result to store in a variable it's not gonna work out so that's where return comes in. def addNum(num1, num2): return num1+num2 answer = addNum(2,3) print (answer) Here you can assign the function answer into an variable so that you can use it later :)

[@HimanshuKumarAN]

Sir why is local variable preffered over global variable? If both have same name. sir please help .

[@chennupatiharika9863]

Local variable:these variables are restricted in tht particular function..i.e.we can access these local variable only tht where we declared tht variable... Global variables:we access these global variables entire the program.....where ever we need we can use.. ....................... So always better to declare globally...

If we have to access global variable inside function definition and both global and local variable have same name

[@icebear6904]

I think then we have to specified Global 'variable name' inside a function to use the same name variable. Otherwise function used the local variable for the operation.

[@ramzy8814]

Just try it yourself and see the result
