我试图将几行csv数据合并为一个长行,因为两个单元格包含相同的数据。例如,请使用以下csv:
one, two, three
1, 2, 3
4, 5, 6
7, 8, 9
1, 1, 1
4, 4, 4
如果两行在第[0]行共享相同的值,我希望第二行附加到第一行。所以我的最终产品应该是这样的:
one, two, three
1, 2, 3, 1, 1, 1
4, 5, 6, 4, 4, 4
7, 8, 9
到目前为止,这是我的尝试:
import csv
uniqueNum = []
uniqueMaster = []
count = -1
with open("Test.csv", "rb") as source:
reader = csv.reader(source)
header = next(reader)
for row in reader:
if row[0] not in uniqueNum:
uniqueMaster.append(row)
uniqueNum.append(row[0])
count = count + 1
for row in reader:
if row[0] in uniqueNum:
uniqueMaster[count].append(row)
with open("holding.csv","wb") as result:
writer = csv.writer(result)
writer.writerow(header)
for row in uniqueMaster:
writer.writerow(row)
事情对我来说很好,但我的脚本只输出以下内容:
one, two, three
1, 2, 3, ['1', '1', '1']
由于两个原因,这显然是错误的。首先,它不会遍历整个csv,其次,附加的值被挤压到一个单元格而不是单个单元格中。如果有人对这项工作有任何建议,我会非常感激!

请改用词典。从代码中间开始(假设我已经声明了一个名为my_dict的dict):
for row in reader:
if row[0] in my_dict.keys():
my_dict[row[0]].extend(row)
else:
my_dict[row[0]]=row
#...now we are at the bottom of your code, writing to the csv
for v in my_dict.values():
writer.writerow(v)
