将字典追加到数据框 [英] append dictionary to data frame

问题描述

我有一个函数，该函数返回像这样的字典:

I have a function, which returns a dictionary like this:

{'truth': 185.179993, 'day1': 197.22307753038834, 'day2': 197.26118010160317, 'day3': 197.19846975345905, 'day4': 197.1490578795196, 'day5': 197.37179265011116}

我正在尝试将此字典附加到数据框，如下所示:

I am trying to append this dictionary to a dataframe like so:

output = pd.DataFrame()
output.append(dictionary, ignore_index=True)
print(output.head())

不幸的是，数据框的打印导致数据框为空.有什么想法吗?

Unfortunately, the printing of the dataframe results in an empty dataframe. Any ideas?

推荐答案

您没有将值分配给结果.

You don't assign the value to the result.

output = pd.DataFrame()
output = output.append(dictionary, ignore_index=True)
print(output.head())
