Pythonでは、たとえ4 / 2のように割り切れる計算でも、/演算子を使った結果はintの2ではなく、floatの2.0になる、というルールがあるためです。 このように非常に身近なfloat型ですが、実は**int型にはない、致命的な「罠」**が潜んでいます。

a = 10 b = 3 result = a * b print(result) # 30 べき乗 (**) result = 2 ** 3 # 2の3乗 print(result) # 8 result = 5 ** 2 # 5の2乗 print(result) # 25 摂氏30度 ...

basic Python project that demonstrates typecasting. We'll create a simple program that allows the user to input different types of data, and the program will typecast those inputs to various other ...

The default behaviour for division has changed between Python 2 and Python 3. In Python 3, dividing an integer by an integer returns a float. e.g.

Python data types define how values are stored, processed, and interpreted in every program. Choosing the right data type improves clarity, reduces errors, and simplifies logic. Understanding ...
