context.py common module

1.context.py write regular expressions, the source code is as follows:

Re Import 
#s target string 
#dict alternative content 
# find the target identifier string inside KEY, to get inside the replacement value d 
# s to replace the inside, and then returns Aberdeen 

def replace (s, dict) : 
    P = "\ $ \ {(.? *)}" 
    the while the re.search (P, S) None Not IS: 
        m = the re.search (P, S) 
        Key m.group = (. 1) 
        value = dict [ Key] 
        S = the re.sub (P, value, S, COUNT =. 1) 
    return S 

S = '{ "MobilePhone,": "admin_user $ {}", "pwd": "admin_pwd $ {}"}' 
Data = { "admin_user": "17,799,801,359", "admin_pwd": "123456"} 

S = Replace (S, Data) 
Print (S)
