Taking input in Python
Python input() function is used to take user input. By default, it returns the user input in form of a string.
Syntax: input(prompt)
The code prompts the user to input their name, stores it in the variable “name”, and then prints a greeting message addressing the user by their entered name.
name = input("Enter your name: ")
print("Hello,", name, "! Welcome!")
Output
Enter your name: w3wiki
Hello, w3wiki ! Welcome!
How to Change the Type of Input in Python
By default input() function helps in taking user input as string. If any user wants to take input as int or float, we just need to typecast it.
How to Print Names in Python
The code prompts the user to input a string (the color of a rose), assigns it to the variable color, and then prints the inputted color.
# Taking input as string
color = input("What color is rose?: ")
print(color)
Output
What color is rose?: Red
Red
How to Print Numbers in Python
The code prompts the user to input an integer representing the number of roses, converts the input to an integer using typecasting, and then prints the integer value.
# Taking input as int
# Typecasting to int
n = int(input("How many roses?: "))
print(n)
Output
How many roses?: 8
8
How to Print Float/Decimal Number in Python
The code prompts the user to input the price of each rose as a floating-point number, converts the input to a float using typecasting, and then prints the price.
# Taking input as float
# Typecasting to float
price = float(input("Price of each rose?: "))
print(price)
Output
Price of each rose?: 50.30
50.3
Find DataType of Input in Python
In the given example, we are printing the type of variable x. We will determine the type of an object in Python.
a = "Hello World"
b = 10
c = 11.22
d = ("Geeks", "for", "Geeks")
e = ["Geeks", "for", "Geeks"]
f = {"Geeks": 1, "for":2, "Geeks":3}
print(type(a))
print(type(b))
print(type(c))
print(type(d))
print(type(e))
print(type(f))
Output
<class 'str'>
<class 'int'>
<class 'float'>
<class 'tuple'>
<class 'list'>
<class 'dict'>
Input and Output in Python
Understanding input and output operations is fundamental to Python programming. With the print() function, you can display output in various formats, while the input() function enables interaction with users by gathering input during program execution.
