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)
