打印CSV数据

想单行打印csv数据。

CSVFile.txt：

abc|xyz|111
def|uvw|222


Python 3.x代码：

with open(csvfile,"r") as csvdata:
for line in csvdata:
fields = line.split("|")
for data in fields:
# do some processing and then
print(data)


这会将数据打印为

abc
xyz
111
def
uvw
222


要以

abc,xyz,111
def,uvw,222


您可以将已处理的data存储在列表中，并在完成每一行的处理后将它们一起打印：

...
row = []
for data in fields:
# do some processing and then
row.append(str(data))
print(",".join(row))
...
