Besides this, we can use the same syntax as in Example 1 to add our two DataFrames together:data_merge2 = pd.merge(data1, # Outer join based on index data2, left_index = True, right_index = True, how = "outer") print(data_merge2) # Print merged DataFrame...
While dealing with pandas DataFrames, we save these DataFrames in the form of the CSV file, sometimes we need to make changes to these existing CSV files.Problem statementGiven a Pandas DataFrame, we have to add it to an existing CSV file....

data_file = osp.join(dataset_path, f'{dataset_name}.tsv') return dict(data_file=data_file, root=dataset_path) def save_video_frames(self, video_path, num_frames=8, fps=-1, video_llm=False): vid_path = osp.join(self.data_root, video_path) vid = decord.VideoReader(vid_path) vi...
