我有一个csv文件,试图从中提取特定的列,但出现keyerror。当我尝试打印CSV的键,我得到这样的结果:
[None, 'Id;"PostTypeId";"ParentId";"AcceptedAnswerId";"OwnerUserId";"LastEditorUserId";"OwnerDisplayName";"LastEditorDisplayName";"UserIdCombined"']
我尝试的代码:
read_file = open ("ml_sample_complete.csv","r") # open input file for reading
col_dict = {}
with open('out.csv', 'wb') as f: # output csv file
writer = csv.writer(f)
with open('ml_sample_complete.csv','r') as csvfile: # input csv file
reader = csv.DictReader(csvfile, delimiter=',')
for row in reader:
print(row.keys())
print(row["Tags"])
col_dict.update(row)
print(col_dict)
read_file.close()
请帮我明白这里有什么问题以及如何纠正它。

您确定您的delimter应该是“”而不是‘;’在dictreader函数中。
