Alternatively using the Pandastolist()function we can return the index of DataFrame as a list. For example, # Get the index as List using tolist() print(df.index.values.tolist()) # Output: # [0, 1, 2, 3] Get Column Index Using the get_loc() ...
具体来说,它通过处理 DataFrame 的每一行(每一行代表一个原子),将它们按残基(residue)分组,每个组被称为一个 "block"。以下是对代码的详细分析,解释如何将数据转化为 "block"。 主要步骤: 循环遍历每个原子(DataFrame 的每一行): df.itertuples()用于按行遍历 DataFrame,每一行都代表一个原子。 从每一行中提取...

更新后尝试.set_index。我用示例数据尝试了这段代码,它是有效的: df = pd.DataFrame({'ANIM': [1, 2, 3], 'NULACT': [400, 500, 600], 'target': [1, 1, 1]}) # without ".set_index(["ANIM", "NULACT"], drop=False)"new_df = pd.DataFrame({'ANIM': [4, 5, 6], 'NULACT'...

TheDataFrame.take()method returns the elements in the specified indices along an axis. Notice that we call thetake()method with a list containing an index and not with the index directly. main.py first_row=df.take([0])print(first_row) ...
