Python - String Formatting

Casting

• Converting one data type to another.

1. Implicit
   • Will be done automatically
   • Example: 2 * 1.5 Output: 3.0
     • The value 2 is converted to float automatically
2. Explicit
   • Has to be specified using built-in functions.
   • Example: int_value = int(1.5)
     • The float value 1.5 is converted to int with the loss of the decimal value.

Function	Description
int()	Converts a specified value into an integer
float()	Converts a specified value into a floating point number
str()	Converts a specified value into a string
list()	Converts a specified value into a list
tuple()	Converts a specified value into a tuple
set()	Converts a specified value into a set
dict()	Converts a specified value into a dictionary
bool()	Converts a specified value into a boolean

String Formatting

• It is the way you can creating string with dynamic content, incorporating variables, expressions, or values within a string.

x = 10
y = 20
s = x + y
print("the first number is",x,"the second number is",y,"Sum is",s)

1. str.format()

message = "the first number is {}, the second number is {}, and sum is {}".format(x,y,s)
print()message

1. F-string

   message = "the first number is {x}, the second number is {y}, and sum is {s}"
   print()message
