According your idea with while loop, here is the fix:
根据你对 while 循环的想法，这里是修复：
#!/usr/bin/env bash
while IFS="|" read -r key data1 data2
do
echo "dictionary['${key}'] = ['${data1}', '${data2}']"
done <"status.txt"

Change your assignment lines to be like this:
将您的分配行更改为如下所示：
key=$(echo $line | cut -d"|" -f1)
And then add the following line
然后添加以下行
printf "dictionary['%d'] = ['%s', '%s']\n" $key $data1 $data2

#!awk -f
BEGIN {
FS = "|"
}
{
printf "dictionary['%s'] = ['%s', '%s']\n", , ,
}

According to the previous answers i could figure out a solution
根据以前的答案，我可以找到解决方案
#!/usr/bin/env bash
while IFS="|" read -r key data1 data2
do
echo "{'${key}' : {'${data1}', '${data2}'}},"
done <"status.txt"
So it will give the result something like as follows
所以它会给出如下结果
{'key1' : {'data1', 'data2'}, 'key2' : {'data1', 'data2'}}
Then you can use this result in any other language.
Example: Python - Convert the above dictionary string to json by 1. json.dumps(result)to convert single quotes tto double quotes 2. json.loads(result)to convert string to json
然后您可以在任何其他语言中使用此结果。示例：Python - 将上述字典字符串转换为 json by1. json.dumps(result)将单引号 t2. json.loads(result)转换为双引号将字符串转换为 json
