Append 字典到循環中的列表 python

Question

我正在嘗試執行類似於以下代碼的操作，但不是像代碼中的最后一行那樣打印，而是在尋找 output 以顯示為字典列表。

import json
studentsList = []
print("Started Reading JSON file which contains multiple JSON document")
with open('students.txt') as f:
    for jsonObj in f:
    studentDict = json.loads(jsonObj)
    studentsList.append(studentDict)
print("Printing each JSON Decoded Object")
for student in studentsList:
    print(studentList) # Output is not looping , I get the following [{'id': 
    1, 'first_name': 'name1'}] but repeated 10 times in row instead it needs 
    to increment id until 10 with 1-10 id). 

謝謝

如果您只是想打印字典列表，為什么不直接print(studentsList)

它看起來像這樣：

import json
studentsList = []
print("Started Reading JSON file which contains multiple JSON document")
with open('students.txt') as f:
    for jsonObj in f:
      studentDict = json.loads(jsonObj)
      studentsList.append(studentDict)
print("Printing the list of JSON Decoded Objects")
print(studentList)

OUTPUT：

如果你想讓你的循環工作：

import json
studentsList = []
print("Started Reading JSON file which contains multiple JSON document")
with open('students.txt') as f:
    for jsonObj in f:
      studentDict = json.loads(jsonObj)
      studentsList.append(studentDict)
print("Printing the list of JSON Decoded Objects")
for student in studentsList:
    print(student)

OUTPUT：

這對我有用，以避免按字母順序對列表進行排序。 pprint 弄亂了排序，因此必須在下面使用才能使其正常工作。

pprint(students_list, sort_dicts=False)
