我们需要做一些类似的事情: final = pd.DataFrame(data)final.columns = ['col1', 'col2'] # Overwrite Column Namesfinal.to_csv('finalFile.csv', index=False) 或者获得一个类似array(to_numpy)的non-indexed结构: # Break existing index alignmentfinal = pd.DataFrame(data.to_numpy(), columns=['...

这两个选项使用相同的方法执行。 可以通过调用 .hide() 而不带任何参数来隐藏索引以便渲染,如果您的索引是基于整数的,这可能很有用。同样,通过调用 .hide(axis=”columns”) 而不带任何其他参数可以隐藏列标题。 可以通过调用相同的 .hide() 方法并传入行/列标签、类似列表或行/列标签的切片来隐藏特定行或列...

Quick suggestion if possible, maybe more of an issue for python core library, but it would be terrific if there was an option within the various writers (to_csv, etc) to check for existence of file and throw error if it already exists. This is desirable for notebook users who repeatedly...
要将数据帧保存到不带索引的csv中,请使用 df.to_csv('file', index = False) 从csv中读取(最初当你整理它时,它仍然在文件中),你可以这样做 df = pd.read_csv('file', index_col = 0) 一旦去掉了索引,您就可以简单地阅读而不必提及index_col,它相当于 df = pd.read_csv('file', index_col =...
