问题描述
我收到以下错误：
NameError跟踪（最近一次通话） 在 81 writer.save（） 82 ---> 83个write_excel（res） 84
NameError：名称'res'未定义
能请你帮忙吗？ ：）
def read_merge(file):
"""" read files and merge the data """
username = pd.read_csv('file.csv',delimiter = ';')
merged_output = pd.read_excel('file-1.xlsx')
merged_output = pd.merge(merged_output,username,how='left',left_on=['h'],right_on=['h2'])
merged_output = merged_output.drop(columns=['h2'])

list_string = ["obj-1","obj-2"]
res = merged_output[~merged_output['Rule'].isin(list_string)]
return res

""""aggregate columns"""
res = res.groupby('Entity_Name').agg({'Rule': ','.join,'Name':'first','Area': 'first','Summary': 'first'}).reset_index()
def write_excel(res):
""""Write Excel document"""
writer = pd.ExcelWriter(r"C:\PATH\output.xlsx",engine = 'xlsxwriter')
workbook=writer.book
worksheet=workbook.add_worksheet('SHEET')
writer.sheets['SHEET'] = worksheet
res.to_excel(writer,sheet_name='SHEET',startcol = 0,startrow = 0)
writer.save()
write_excel(res)
解决方法
代码write_excel(res)的最后一行引用了代码中未定义的变量res。
错误消息NameError: name 'res' is not defined应该为您提供正在发生的事情的线索
