使用python生成随机json数据

需要以这种格式生成随机json数据

list=['20','30','50','1','200']

for n in list : 
    data= 
          {
           "total_members_present":1000    
           "count": n  
           "total_members_now":980 
         }

它应该一直持续到列表结束。

使用简单的迭代

Ex:

lst = ['20','30','50','1','200']
result = []
start = 1000
for i in lst:
    data = {
           "total_members_present":start,    
           "count": i,
           "total_members_now":start - int(i)
          }
    start = data["total_members_now"]
    result.append(data)

print(result)

[{'count': '20', 'total_members_now': 980, 'total_members_present': 1000},
 {'count': '30', 'total_members_now': 950, 'total_members_present': 980},
 {'count': '50', 'total_members_now': 900, 'total_members_present': 950},
 {'count': '1', 'total_members_now': 899, 'total_members_present': 900},
 {'count': '200', 'total_members_now': 699, 'total_members_present': 899}]

输出：

lst = ['20','30','50','1','200']
result = []
start = 1000
for i in lst:
    data = {
           "total_members_present":start,    
           "count": i,
           "total_members_now":start - int(i)
          }
    start = data["total_members_now"]
    result.append(data)

print(result)

[{'count': '20', 'total_members_now': 980, 'total_members_present': 1000},
 {'count': '30', 'total_members_now': 950, 'total_members_present': 980},
 {'count': '50', 'total_members_now': 900, 'total_members_present': 950},
 {'count': '1', 'total_members_now': 899, 'total_members_present': 900},
 {'count': '200', 'total_members_now': 699, 'total_members_present': 899}]

直截了当地说：

不要使用Python保留名称作为变量（

list

，

dict

等），以避免它们被混淆

输出：

[{'count': 20, 'total_members_now': 980, 'total_members_present': 1000},
 {'count': 30, 'total_members_now': 950, 'total_members_present': 980},
 {'count': 50, 'total_members_now': 900, 'total_members_present': 950},
 {'count': 1, 'total_members_now': 899, 'total_members_present': 900},
 {'count': 200, 'total_members_now': 699, 'total_members_present': 899}]

那么，在哪一点上你感到困惑？我觉得这不是随机的。在循环之前初始化你的值，并在循环中创建字典，进行计算并将字典添加到列表中。为什么不使用random.shuffle使其更随机？
