数组之间的Python CSV双引号

Question

我正在处理CSV文件。如何在数组之间添加双引号？

marketplaces = ['amazon', 'ebay', 'alibaba', 'walmart']
with open('example.csv', 'a', encoding="utf-8") as f:
# Writing data to a file
writer = csv.writer(f, delimiter=",", quotechar='"', lineterminator="n", quoting=csv.QUOTE_ALL)
writer.writerow(marketplaces)

打印

"amazon","ebay","alibaba","walmart"

我想要这个

"amazon,ebay,alibaba,walmart"

Answer 1

完成！

marketplaces = ['amazon', 'ebay', 'alibaba', 'walmart']
with open('example.csv', 'a', encoding="utf-8") as f:
# Writing data to a file
f.write('"')
for marketplace in marketplaces:
if marketplace != marketplaces[len(marketplaces)-1]:
f.write(marketplace + ",")
else:
f.write(marketplaces)
f.write('"n')

输出

"amazon,ebay,alibaba, walmart"
