问题描述
有必要在字典中为键和值添加双引号.我试图用正则表达式来做，但是我不擅长(字典可以有两种类型:1)a = {x:2，y:1，z:-3，b:1}2)a = {x:226/185，y:9/37，z:-409/185，b:133/185}我们需要找到两种类型的通用解决方案.
It is necessary to add double quotes for the key and value in the dictionary.I tried to do it with regular expressions, but I’m not good at it (The dictionary can be of two types 1) a = {x: 2, y: 1, z: -3, b: 1}2) a = {x: 226/185, y: 9/37, z: -409/185, b: 133/185}We need to find a universal solution for both types.
gg={x: 2, y: 1, z: -3, b: 1}
gg1={x: 226/185, y: 9/37, z: -409/185, b: 133/185}
nn="{x: 2, y: 1, z: -3, b: 1}"
nn2="{x: 226/185, y: 9/37, z: -409/185, b: 133/185}"
yy=re.sub(r'(\w*): (\d*)',r'"\1": "\2"',nn)
yy2=re.sub(r'(\w*): (\d*)',r'"\1": "\2"',nn2)
print(yy)
print(yy2)
{"x":"2"，"y":"1"，"z":" -3，"b":"1"}{"x":"226"/185，"y":"9"/37，"z":" -409/185，"b":"133"/185}
{"x": "2", "y": "1", "z": ""-3, "b": "1"}{"x": "226"/185, "y": "9"/37, "z": ""-409/185, "b": "133"/185}
推荐答案
import re
nn="{x: 2, y: 1, z: -3, b: 1}"
nn2="{x: 226/185, y: 9/37, z: -409/185, b: 133/185}"
dict_str = lambda data : re.sub(r'(\w+):\s*(-?\d[\d/.]*)',r'"\1": "\2"',data)
for i in [nn,nn2] :
var1=dict_str(i)
print(var1)
# if you want an actual dictionary from var1 you can uncomment the lines below
#var2 = var1.replace('{','').replace('}','').replace('"','')
#var3 ={ j.split(':')[0] : j.split(':')[1] for j in [ k for k in
#var1.split(',') ] }
#print(var3)
