​

#STRING FORMAT METHOD 1

age = 66

txt = "My name is Buddy, and I am {}"

print("OUTPUT 2 : ",txt.format(age))

​

#STRING FORMAT METHOD 2

quantity = 4

productid = 1012

price = 49.95

myorder = "I want {} pieces of product {} for {} rupees."

Python Type Conversion

#TYPE CONVERSION

#convert from int to float:

x = float(1)

​

#convert from float to int:

y = int(2.8)

​

#convert from int to complex:

z = complex(1)

​

print(x)

print(y)

print(z)

print(type(x))

print(type(y))

print(type(z))
