@, $, %) and since Python is a case sensitive language name and Name are considered as two different variables.name = 'your name'
Name = 'please provide your full name'
print(name) # Output: your name
print(Name) # Output: please provide your full nameSince Python distinguishes between uppercase and lowercase letters, changing the capitalization of a variable name creates a new, separate variable.
x = 10 in Python without declaring a type? x = 10 in without declaring a type, Python automatically determines the data type based on the assigned value. Since 10 is a whole number, x will be assigned the integer (int) type.x = 10
print(type(x)) # Output: <class 'int'>This code swaps the values of a and b, so the output will be:
10, 5# symbol and are used to add brief explanations within the code.# This is a single-line comment

This is a multi-line comment.
It can span multiple lines.

The print(x, y) statement prints the values of x and y, separated by a space.
print() function. name, age, and city. Assign them your name, age, and city respectively. Then, use the print() function to display their values in a sentence.name = 'Vishal'
age = 27

print('Sum of x and y is :',x+y)
print('Difference of x and y is :',x-y)
print('Product of x and y is :',x*y)

Product of x and y is : 50
Quotient of x and y is : 0.5
