我正在尝试使用 Python 从存档中提取一些信息。该文件的一部分是:

stdout = open("results.txt", "w")
pattern = re.compile(r'^\d+[.]\s')

listOrg = []
def group_separator(line):
return line=='ID: '
with open('Microarray/PlatformsMicroarray.txt') as f:
for key,group in itertools.groupby(f,group_separator):
# print(key,list(group)) # uncomment to see what itertools.groupby does.
if not key:
data={}
for item in group:
for line in f:
if pattern.search(line):
listOrg.append(line)
if pattern2.search(line):
#field,value=line.split(':')
listOrg.append(line)
if pattern3.search(line):
listOrg.append(line)
if pattern4.search(line):
listOrg.append(line)
for item in listOrg:
stdout.write("%s" % item)
stdout.close()
如何连接信息以便以 .csv 格式写入存档？
最佳答案
csv 模块是您选择的武器。
with open("path/to/out.csv", "wb") as out:
writer = csv.writer(out)
for line in whatever_your_input_is:
writer.writerow(line)
在这种情况下，看起来 listOrg 是您解析的输入，所以您会这样做
...
for line in listOrg:
writer.writerow(line)
