input() and print() functions of Python programming

-

input() and print() functions of Python:

Every computer  program has to communicate with the outside world. To this purpose every programming language has special input and output functionalities. You have need to understand. Python programming provides numerous built-in functions. That are ready available to you at the Python programming .  input() and print() are widely used for standard input and output operations respectively.

input() function:

The input() function is used  to read input from the keyboard. If the input function is called, the program flow will be stopped until the user has enter an input and has ended the input with the return key. The text of the optional parameter, that is the prompt, will be printed on the screen. The input of the user will be interpreted. If the user puts in an integer value, the input function returns this integer value. If the user on the other hand inputs a tuple, the input function will return a tuple. 

For Example: Writ e program to demonstrate use of input() function.

# This is example of input() function

str1 = input("Enter your First Name: ")

str2 = input("Enter your Last Name: ")

print("Your name is: ", str1)

print("Your name is: ", str2)

 Output:


 

print() function:

This function is used to prints the given object to the standard output device (screen) or to the text stream file. The print() function is always used for display output on screen.

Syntax:

            print(“String is here”)

For Example: Write a program to demonstrate the use of print() function.

# This is example of print() function

rollno=input("Roll No of Student:")

sname = input("Enter  Name of Student: ")

sclass = input("Enter Class of Student: ")

scity = input("Enter City of Student:")

mno = input("Enter Mobile Number:")

print("...................................................")

print("--------Student Details----------")

print("...................................................")    

print("Roll No     : ", rollno)

print("Name       : ", sname)

print("Class         : ", sclass)

print("City         : ", scity)

print("Mobile No.   : ", mno)

 Output:



 

Output formatting in python:

Programmer have need to format our output to make it look attractive as per yours needs. This time you use .format() method. This method is visible to any string object in python programming. Curly braces {} are used as placeholders. We can specify the order in which it is printed by using index.

For Example: Write the demonstrate the use of print formatting.

#program for formatting output in python

print('This is my Name: {0} {1}'.format('Jaypal','Shinde'))

print('This is my Name: {1} {0}'.format('Jaypal','Shinde'))

Output:

Iterative Control: Iterative control statement is also known as looping statement.   An iterative control statement is control statement providing the repeated execution of a set of instructions. An iterative control structure is a set of instructions and the iterative control statement controlling their execution. Because of their repeated execution. These are following looping Statements used in python programming- While loop: It is many times used, when the number of times the loop to be executed. In this loop first check the condition, if the condition is true then if executes a statement, at the end of loop increment/decrement is done to change in variable value. After execution it again checks the condition and if the condition is found to be true, it again executes the block of statement. Statement is executed continuously until the condition is true, otherwise condition is found false, it exit out of loop. Syntax: while test_expression:     ...

operator of python

Operators: An operator is a symbol that represents an operation that may be performed on one or more operands. For Example - The + symbol represents the operation of addition. An operand is a value that a given operator is applied to, such as operands 3 and 4 is the expression 3 + 4. A unary operator operates on only one operand, such as the negation operator in -9. A binary operator operates on two operands, as with the addition operator. Most operators in programing languages are binary operators. An operator is a symbol that represents an operation that may be performed on one or more operands. Operators that take one operand are called unary operators. Operators that take two operands are called binary operator.  These are the following operators are used in python- Arithmetic Operators: Arithmetic operators are used to perform mathematical operations like addition, subtraction, multiplication etc. Python provides the arithmetic operators like +, - , * and /. It operato...

Precedence of operators and converstion in python programming with subtable example

  Precedence of operators : Precedence determine a series of steps carried out to be accomplished a task. The way we commonly represent expressions, in which operators appear between their operands, it is referred to as infix notation. For example the expression 4 + 5 is in infix notation since the + operator appears between its two operands, 4 and 5. There are other ways of representing expression called prefix and postfix notation in programming language, which operators are placed before and after their operands, respectively.             The expression 4 + (3*5) is also in infix notation. It contains two operators, + and *. The parentheses denote that (3*5) is sub expression. Therefore, 4 and (3*5) are the operands of the addition operator, and thus the overall expression evaluates to 19. What if the parentheses were omitted, given below             4 + 3 * 5 T...
