Print Function in python

The print function in Python is a powerful tool for displaying information to the screen.

Syntax: -

print(object(s), sep=separator, end=end, file=file, flush=flush)
  • object(s): Any Python object (e.g., string, list, tuple) that you want to print. It will be converted to a string before being displayed.
  • sep: Optional. Specifies how to separate multiple objects if you’re printing more than one. The default separator is a space.
  • end: Optional. Determines what to print at the end of the output. The default is a newline character (‘n’).
  • file: Optional. An object with a write method where the output will be directed. The default is sys. stdout.
  • flush: Optional. A Boolean value indicating whether the output should be flushed (True) or buffered (False). The default is False.

Print a single message:

print ("Hello, World!")

Print multiple objects:

print ("Hello", "how are you?")

Specify a custom separator:

print ("Hello", "how are you?", sep="---")

Input () Function

The input function in Python is a powerful way to interact with users and obtain input from them.

Syntax: –

 user_input = input(prompt)

prompt (optional): A string that displays a message to the user before accepting input.

For Example, taking the user’s name and age as input:

name = input ("Please enter your name: ")
age = input ("Please enter your age: ")
print ("My name is “, Name)
print (“I am” ,age, “ year old ”)

While Processing information for numeric type, we need to tell the interpreter about it.

Example 1

age=int (Input (“Enter your age”))
Print(age)

Example 2

temperature=float (Input (“Enter the temperature”))
Print(temperature)

#Write a Python program to add two numbers

num1 = 4.7

num2 = 7.5

# Add two numbers

sum = float(num1) + float(num2)

# Display the sum

print ('The sum of {0} and {1} is {2}’. format (num1, num2, sum))

#Write a Python program to add two numbers provided by user.

# Store input numbers

num1 = input ('Enter first number: ')

num2 = input ('Enter second number: ')

# Add two numbers

sum = float(num1) + float(num2)

# Display the sum

print ('The sum of {0} and {1} is {2}’. format (num1, num2, sum))

#Write a Python Program to Find the Square Root.

num = float (input ('Enter a number: '))

num_sqrt = num ** 0.5

print ('The square root of %0.3f is %0.3f'% (num, num_sqrt))

#Write a Python Program to Calculate the Area of a Triangle.

a = float (input ('Enter first side: '))

b = float (input ('Enter second side: '))

c = float (input ('Enter third side: '))

# calculate the semi-perimeter

s = (a + b + c) / 2

# calculate the area

area = (s*(s-a) *(s-b) *(s-c)) ** 0.5

print ('The area of the triangle is %0.2f' %area)
