[英]How to convert a table using pandas.dataframe?
我有一本字典(数组)。 我需要他的外表与照片中的一样。 怎么做?
我的代码
array = {1: {2016: 22818888925.021294, 2017: 23215791927.55883, 2018: 24241415053.75489, 2019: 25526831987.89783, 2007: 18183059018.027966, 2008: 16868527277.51174, 2009: 18331809529.53519, 2010: 19724006864.797657, 2011: 20392912788.825798, 2012: 19580849153.840134, 2013: 22084393933.539394, 2014: 22030084567.47173, 2015: 21700822555.267574}, 2: {2016: 15081873888.10038, 2017: 15377071873.462284, 2018: 16253879799.12362, 2019: 16517025291.019705, 2007: 10038529774.615318, 2008: 11611749842.042978, 2009: 12040185617.510305, 2010: 12508816879.258118, 2011: 13711111085.100977, 2012: 13219008951.675236, 2013: 14209627046.021126, 2014: 15371996764.61913, 2015: 14417938720.997215}, 6: {2016: 0.6609381349660216, 2017: 0.6623539667069717, 2018: 0.6705004539991144, 2019: 0.6470456380505956, 2007: 0.5520814602571774, 2008: 0.6883677306864346, 2009: 0.6567919876164886, 2010: 0.6341924825418297, 2011: 0.6723468700662476, 2012: 0.6750988605150847, 2013: 0.6434239077958611, 2014: 0.6977729348945159, 2015: 0.6643959547744175}})

如果你使用下面的代码,你应该得到你想要的:
new_df = pd.DataFrame(df.unstack()).transpose()
print(new_df)
This works by converting your original df to a series with the MultiIndex of all current columns + the year via pd.DataFrame.unstack , then converting the resultant series back into a dataframe with one row by feeding that series into pd.DataFrame (resulting in一长列,标题为 0),然后使用pd.transpose将该列转置为您想要的一长行。
