Otherwise it also throws a RuntimeError: The library requires Python 3.6 or newer. 1.0.0a0 Once constructed you cannot add, remove or update elements from the list. Frozen set is immutable type. 本連載ではこれまでに、整数、実数(浮動小数点数)、文字列などの値(オブジェクト)について紹介をしてきた。これらの値の性質や、それらに対して行える計算機能はそれぞれ異なっていて、通常、プログラミング言語ではそうしたデータの種類を「データ型」として分類している。Pythonでは整数にはint型、浮動小数点数にはfloat型、文字列にはstr型という名前が付けられて分類されている。 これらのデータ型は基本的に、一度に1つだけの値を扱える。だが、プログラムでは複数個のデータを一括して扱 … An immutable thing cannot be changed.
