I am parsing a text file which contain python "string" inside it. For e.g.:

'my_home1' in houses.split(',') and '2018' in iphone.split(',') and 14 < mask

for the example above, I wrote a possible dictionary:

dict = {'house' : 'my_home1,my_home2', 'iphone' : '2015,2018', 'mask' : '15' }

but dict is not know in advance and will be adapted during the running time of the python script.

I would like to replace all the appearance of keys inside the string above in a dynamic way and then to evaluate the expression.

At the end I found a solution to my problem:

text = "'my_home1' in houses.split(',') and '2018' in iphone.split(',') and 14 < mask"
dict = {'house' : 'my_home1,my_home2', 'iphone' : '2015,2018', 'mask' : '15' }expression = 'false'for key in dict.keys():if isinstance(dict.get(key), str):text = re.sub(key, '\'{}\''.format(dict.get(key)), text)else:text = re.sub(key, dict.get(key), text)eval(text)
