The idea (Explicit Type Conversion). In explicit conversion (also called type casting) the programmer deliberately converts a value from one type to another using a constructor function such as float(), int() or str(). This is different from implicit conversion, where Python changes the type on its own during mixed-type arithmetic. Converting int → float is always safe: no information is lost, the value just gains a fractional part .0.
Program
# prog5-5.py
# Program of explicit type conversion from int to float
marks1 = 45
marks2 = 42
total = marks1 + marks2 # int + int -> int
totalFloat = float(total) # explicit int -> float
print(total)
print(totalFloat)
print(type(totalFloat))
Expected output
87
87.0
<class 'float'>
Key lines
total = marks1 + marks2— both operands areint, so the result 87 is anint; Python does not convert anything here. …
