Python使用Excel将数据写入多个sheet

import pandas as pd
df1 = pd.DataFrame({\'a\':[3,1],\'b\':[4,3]}) 
df2 = df1.copy()
with pd.ExcelWriter(\'F:\\\\python入门\\\\数据2\\\\output.xlsx\') as writer:
  str1 = [\'a\',\'b\',\'c\',\'d\',\'e\',\'f\',\'g\',\'h\',\'i\',\\
      \'j\',\'k\',\'l\',\'m\',\'n\',\'o\',\'p\',\'q\']
  for i in str1:
    name = str(i)
    df1.to_excel(writer, sheet_name= name)
writer.save()
writer.close()
