python - 从 JSON 文件中提取值并在 Python 中执行计算
问题描述
我目前有一个脚本，它从 JSON 文件中提取值并将它们保存为变量。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。

任何帮助，将不胜感激。
谢谢！
解决方案
如果您了解您使用的列表推导式，则修改起来非常简单。
y_coords = ([float((k['Y'])) * 100 for k in data['a']])
您应该能够为其他示例执行此操作
