What is the best way (Python 3) to loop through dict keys, examine the
string, change them if needed, and save the changes to the same dict?
So for input like this:
{'Mobile': 'string', 'context': '<malicious code>', 'order': '7',
'time': 'True'}
I want to booleanize 'True', turn '7' into an integer, escape
'<malicious code>', and ignore 'string'.
Any elegant Python way to do this?

I think JSON could be of some use, but I've not used it yet,
otherwise something like this could do it:
#!/usr/bin/python
from cgi import escape
def convert(string):
for conv in (int, lambda x: {'True': True, 'False': False}[x],
escape):
try:
return conv(string)
except (KeyError, ValueError):
pass
return string
d = {'Mobile': 'string',
'context': '<malicious code>',
'order': '7',
'time': 'True'}
print d
for key in d:
d[key] = convert(d[key])
print d
$ ./conv.py
{'Mobile': 'string', 'order': '7', 'context': '<malicious code>',
'time': 'True'}
{'Mobile': 'string', 'order': 7, 'context': '<malicious
code>', 'time': True}
