Python call function from another function

Python call function from another function : The function is called by the function and breaks the problem in the small problems. The function will involve such as the help () and has min () to get minimum value and print () an object to the terminal. The user-defined function is the functions that are used to create and help. The anonymous that are called as the lambda function and not declared the standard-def keyword.

How to call the calling function:-

The function calls another function is called the “calling function”.
Execution:-
The stack is used for the execution of the function calls and the function is involved than calling the pushed stack.
Then the function completes the execution and return the calling function is popped from the stack and executed.
The function will have a new symbol used for the local variables of the function.
The variables look in the local symbol table in local tables.

The components are as follows:-

1. The keywords def are used to start the function header.
2. The name of the function is used to identify and function will follow the same rules for writing the identifiers.
3. The argument trough which we pass the values are optional.
4. The Colon is also used to mark the end of function n header.
5. Return function is used to return the value of the function.

Function definition:-
The block is reusable that is used to perform a specific action.

 Advantages:-

1. Reduce duplication code.
2. Decompose the complex problem into simple pieces.
3. Reuse the code.
4. Improve the clarity of code.
5. Information is hidden.

Types of functions are:-

1. Build in functions
2. User defined functions

1. Python creating the function:-

The function is created by def keyword and statements in block of code function and defined as,
def function():
pass
The def keyword is followed by function name and the round bracket, colon.
The indented statement will form the body of function.
The function is needed we call the function and if we call the function and the function body are executed.
Example:-
def square(x)
return(x*x)
def SumofSquare (Array, n):
sum=0
for i in range (n):
squaredvalue
squaredvalue=square (Array[i])
sum+=squared value
return sum
array=[1,2,3,4,5,6,7,8,9,10]
n=len (Array)
total=sumofsquares (Array, n)
print(“Sum of the Square of List of Numbers:” Total)
Output:-
Sum of the Square of List of Numbers: 385

2. Calling the function from another function within the same class:-

In this the following example, class method of function1 will call the function2 from class in same class in the python language.
Example:-
def__init__ (self):
self.String1=”Hello”
self.String1=”World”
defFunctional(self):
self.Function2 ()
print(“Function1:” self.String2)
return
def Function2(self):
print(“Function2:” self.String1)
return
object=Main ()
object.Function1()
Output:-
Function2: Hello
Function1: World

3. Calling parent class function from child class function:-

The example is the child class that invokes parent class method and the class will inherit the attributes from parent class.
Example:-
def__init_ (self):
self.String1=”Hello”
self.String2=”World”
def Function2 (self):
print(“Function2:” self.String1)
return
classChild (Parent):
def Function2 (self):
print(“Function1:” self.String2)
return
Object1=Parent ()
Object2=child ()
Object2.Function1 ()

Output:-
Function2: Hello
Function1: World
