我有一个文本文件,我想在python中使用字典数据结构将所有带aaa的行归为一组,然后发送到一个名为aaa_file的文件中,并与bbb做同样的事情。
hey student1 aaa 123 yes
hi student2 bbb 321 yes
hello student3 aaa 432 no
hi student4 bbb 589 yes
我想在python中使用字典数据结构将所有带aaa的行归为一组,然后发送到一个名为aaa_file的文件中,并对bbb做同样的事情。
我试过的代码。
import json
import sys
with open("text.txt", 'r') as f:
lines = f.readlines
newDict{}
for line in lines
unit = line.split()
newDict[unit[2]]=unit[0:]
print(json.dumps(newDict, indent = 4))
这段代码将帮助你
import json
import sys
from collections import defaultdict
with open("text.txt", 'r') as f:
lines = f.readlines()[1:]
newDict = defaultdict(list)
for line in lines:
print(line)
unit = line.split(" ")
newDict[unit[2]].append(unit)
print(json.dumps(newDict, indent = 4))
for key in newDict:
with open("{}_list.json".format(key), "w") as f:
for i in newDict[key]:
f.write(" ".join(i) + "\n")
