从JSON文件中提取值并在Python中执行计算

Question

我目前有一个脚本，可以从JSON文件中提取值并将其保存为变量。但是，在保存为变量之前，我需要将所有这些值乘以100

with open("match.json",'r') as f:
    data = json.load(f)
    f.close()

coords = ([(k['X'], k['Y']) for k in data['a']])
x_coords = ([(k['X']) for k in data['a']])
y_coords = ([(k['Y']) for k in data['a']])

这是我正在使用的JSON文件

Answer 1

您可以尝试类似的方法（使用map函数）

coords = list(map(lambda x: (float(x['X'])*100, float(x['Y'])*100), y['h']))

Answer 2

如果您理解所使用的列表理解，那么修改就非常简单

y_coords = ([float((k['Y'])) * 100 for k in data['a']])

对于其他示例，您应该能够做到这一点
