在上述代码中,我们首先将dict2转换为一个DataFrame对象,然后使用concat函数将它与之前的DataFrame对象(df)合并。参数ignore_index=True表示重新索引合并后的DataFrame。 最终,我们得到了一个包含两个字典数据的DataFrame对象(df)。 这种方法可以用于将任意数量的字典合并成一个DataFrame,只需要在concat
pandas.DataFrame.to_dict DataFrame.to_dict(orient=‘dict’, into=<class ‘dict’>) Convert the DataFrame to a dictionary. The type of the key-value pairs can be customized with the parameters (see below). Parameters orient[str {‘dict’, ‘list’, ‘series’, ‘split’, ‘records’, ...
Method 2: Using a List Comprehension with Zip() This is another approach towards our goal and makes use of list comprehensions to convert list to list of dictionaries. It iterates over the test_list in chunks which is determined the length of the key_list thereby creating dictionaries which ...

在前面的代码中,我们使用了列表字典来创建DataFrame。此处,字典的关键字等效于列,而值等效于DataFrame的行。接下来我们使用字典列表(list of dictionaries)来创建一个DataFrame: # Pandas DataFrame by lists of dicts. # Initialise data to lists. data =[ {'Name': 'Vijay', 'Age': 23},{'Name': 'Sundar...
