#This is my 1st python program

#Variables- it could strings, integer, f;oat, boolean.

#string 
name = "krishna"
print(f" Hello user your name is {name}")
food = "paneer"
print (f"Your fav food is {food}")
#f helps in formating what u write inside make sure to use {} for variable

#Integer- as u know its a whole no. and dont put this under "" because it becomes a text

num_of_yr_of_edu = 12
print (f"Hello {name} your fav food is {food} your age is is {age} and you were born in {dob} with {num_of_yr_of_edu} years of education")
#whenever u write more than word on the left write like this new_word this tells python they are 2 diff words they are called snake case

#Floats- is for decimal numbers
price = 99.99

distance = 12.500

#so you can aslo add km or $ but outside the {} as required front or back

#BOOlean-this one's nice it either is True or False with cap T or F and u can with this with else and if statement

#Typecasting= this changes from one variable to another using str(), bool(), int(), float()

# integer to float is easy, string to boolean is used to checck if the user has enterred their name or not

#input()  it takes info from the user in string only to form any other arithmatic func u need to typecaste it using int() or float()
name = input("your name  bbg?")

print(f"Hello {name} your age is {age}")

#exercise-1 we need to ask user length and width of rectangle and calculate area for it

length = int(input("describe the length of ur rectangle")) #ive converted string into int to perform arth operation
