在Python中,列表的长度可以通过内置函数`len()`来获取。 - **选项A**:`len(list)`是Python标准方法,用于获取任何可迭代对象的元素数量,正确。 - **选项B**:`size(list)`不是Python列表的方法,可能是其他库(如NumPy)的函数,错误。 - **选项C**:`length(list)`不是Python内置函数或列表方法,错误。 -...
‘s’ in the string. The comprehensioniterates over the stringand includes it in the list if it matches ‘s’. The length of the count list is calculated using thelen()function. This effectively gives the count of occurrences of the character ‘s’. The result of the count is printed ...
