问题描述
遍历一大堆.mp3链接以获取元数据标记并将其保存到Excel文件.导致此错误.感谢您的帮助.谢谢.
Iterates over a big list of .mp3 links to get the metadata tags and save it to an Excel file. Results in this error. I appreciate any help. Thanks.
#print is_connected();
# Create a Pandas dataframe from the data.
df = pd.DataFrame({'Links' : lines ,'Titles' : titles , 'Singers': finalsingers , 'Albums':finalalbums , 'Years' : years})
# Create a Pandas Excel writer using XlsxWriter as the engine.
writer = pd.ExcelWriter(xlspath, engine='xlsxwriter')
# Convert the dataframe to an XlsxWriter Excel object.
df.to_excel(writer, sheet_name='Sheet1')
#df.to_excel(writer, sheet_name='Sheet1')
# Close the Pandas Excel writer and output the Excel file.
writer.save()
Traceback (most recent call last):

return _arrays_to_mgr(arrays, data_names, index, columns, dtype=dtype)

index = extract_index(arrays)

raise ValueError('arrays must all be same length')
ValueError: arrays must all be same length
推荐答案
您可以执行此操作以避免该错误
you can do this to avoid that error
a = {'Links' : lines ,'Titles' : titles , 'Singers': finalsingers , 'Albums':finalalbums , 'Years' : years}
df = pd.DataFrame.from_dict(a, orient='index')
df.transpose()
