What is Python Casting with example?

Question

ICSM Computer · Answer

Python, casting (also called type conversion) means converting a value from one data type to another.
There are two main types:
1. Implicit Casting (Type Conversion)
Done automatically by Python (no data loss).
For example, when combining an integer with a float:
x = 5      # int
y = 2.5    # float
z = x + y  # Python automatically converts `x` to float
print(z)   # 7.5
print(type(z))  # andlt;class 'float'andgt;
2. Explicit Casting (Type Conversion)
Done manually by the programmer using functions:
int() → converts to integerfloat() → converts to floating-point numberstr() → converts to stringbool() → converts to boolean
Examples:
# String to integer
a = int("10")
print(a, type(a))   # 10 andlt;class 'int'andgt;
# Float to integer (decimal part is truncated)
b = int(9.8)
print(b, type(b))   # 9 andlt;class 'int'andgt;
# Integer to float
c = float(5)
print(c, type(c))   # 5.0 andlt;class 'float'andgt;
# Number to string
d = str(123)
print(d, type(d))   # "123" andlt;class 'str'andgt;
# String to float
e = float("3.14")
print(e, type(e))   # 3.14 andlt;class 'float'andgt;
# Any non-zero number becomes True
f = bool(1)
print(f, type(f))   # True andlt;class 'bool'andgt;
# Empty string or 0 becomes False
g = bool("")
print(g, type(g))   # False andlt;class 'bool'andgt;
Summary Table of Casting Functions in Python:
Function
Converts To
Example
int(x)
Integer
int("12") → 12
float(x)
Floating number
float("3.5") → 3.5
str(x)
String
str(99) → "99"
bool(x)
Boolean
bool(0) → False

Function	Converts To	Example
`int(x)`	Integer	`int("12") → 12`
`float(x)`	Floating number	`float("3.5") → 3.5`
`str(x)`	String	`str(99) → "99"`
`bool(x)`	Boolean	`bool(0) → False`
