Python2是一种编程语言,它是Python编程语言的旧版本。它相当于带有pandas DataFrame(df)的get_dummies函数。 get_dummies是pandas库中的一个函数,用于将分类变量转换为虚拟变量。它将分类变量的每个取值都转换为一个新的二进制变量,并为每个取值创建一个新的列。这些新的列包含了原始数据中的分类信息,并用0和1表示。
index.tolist()) # Example 5: Get maximum row number # Using idxmax() row_num = df['Fee'].idxmax() # Example 6: Get minimum row number # Using idxmin() row_num = df['Fee'].idxmin() To run some examples of getting the row number of pandas DataFrame, let’s create DataFrame ...
