What is a function in Python?
• Python, work is a group of private sector executives. • Help with exercise to break into smaller and similar programs. As our program has grown a lot, the job creates a more manageable system. • In addition, repairs are avoided and make them recyclable. • Python Interview Questions & Answers.
Syntax of Function
def function_name(parameters): """docstring""" statement(s) • Python training institute in Chennai
The definition of the definition above is shown in the following sections.
1. The key word of the TKR is a sign of the beginning of a leader. 2. Name of activity to identify inappropriately. The name of the job is the same as Python's writings. 3. A guide (a reason) used for the cost of performance. They prefer. 4. Time (:) to show the end of the leader.

Docstring:
•The first presidential chain of chain of documents and chains of chains. It is used to describe a few words, what's working at the wedding. •While selecting, the documents are a good program. Apart from where to find it was the first night, always write your number. For example: Try to keep the bottom of the waste, Python watching out. >>> print(greet.__doc__) This function greets to the person passed into the name parameter
The return statement:
After this, it is used to leave the work and return to the place known. Python interview questions and answers
Syntax of return:
return [expression_list] This text may include quantitative expressions and return values. If there are no details on the identification or proof it is not working, then the task will return to the item. For example: >>> print(greet("May")) Hello, May. Good morning!

Example of return:
def absolute_value(num): """This function returns the absolute value of the entered number""" if num >= 0: return num else: return -num # Output: 2 print(absolute_value(2)) # Output: 4 print(absolute_value(-4))
How Function works in Python?
Scope and Lifetime of variables:
• The size of a part of the program depends on the known changes. Articles and trends are defined in an unprecedented act. Therefore, they have a place to live. • A period of change in your life using a set of variables. Changing the life of the task during the operation is carried out. • When it is broken, let's go back to the action. Therefore, the action does not tell the cost of the old call.
Below is an example showing the effectiveness of the work. def my_func(): x = 10 print("Value inside function:",x) x = 20 my_func() print("Value outside function:",x) Output: Value inside function: 10 Value outside function: 20
Types of Functions:
• Basically, we can divide up two types of the following activities: • 1. Build up activities - jobs built for Python. • 2. Operations defined in the user - activity defined in the user.
