Python 如何从文件中每行的第三个单词生成字典条目
我有一个文本文件:Python 如何从文件中每行的第三个单词生成字典条目,python,dictionary,key,key-value,Python,Dictionary,Key,Key Value,我有一个文本文件: 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有aaa的行分组在一起,并发送到一个名为aaa_file的文件,然后对bbb执行相同的操作 我试过的代码: import json import sys with open("text.txt", 'r') as f: line
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有aaa的行分组在一起,并发送到一个名为aaa_file的文件,然后对bbb执行相同的操作
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))
此代码将帮助您实现这一点
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")
输出
{
"aaa": [
[
"hey",
"student1",
"aaa",
"123",
"yes"
],
[
"hello",
"student3",
"aaa",
"432",
"no"
]
],
"bbb": [
[
"hi",
"student2",
"bbb",
"321",
"yes"
],
[
"hi",
"student4",
"bbb",
"589",
"yes"
]
]
}
