Convert String in Dictionary List-CodePudding

I am new to python. I code below however I am hitting exception.

Input

studId=ValueA,studName=valueB;studId=ValueC,studName=ValueD

Output if list

[{'name':'ValueA','value':'valueB'},{'name':'ValueC','value':'valueD'}]

Output

ValueA

My code

str = "studId=ValueA,studName=valueB;studId=ValueC,studName=ValueD"

stud_list = dict(item.split("=") item.split(",") for item in str.split(";"))

for stud in stud_list :
  print(stud['studName'])

exception

SyntaxError: invalid syntax

CodePudding user response：

Update the structure while loading the data

str = "studId=ValueA,studName=valueB;studId=ValueC,studName=ValueD"

stud_list = [dict(it.split("=") for it in item.split(",")) for item in str.split(";")]

for stud in stud_list :
  print(stud['studName'])

While I also enjoy comprehensions, more readably, one could:

inStr = "studId=ValueA,studName=valueB;studId=ValueC,studName=ValueD"

dict_list = []

for d in inStr.split(';'):
  dict_list.append({})
  for pair in d.split(','):
    k, v = pair.split('=')
    dict_list[-1][k] = v

print(dict_list)
