Question

I have conditional string like below ,

condition1 = "((2=2) or (3=1)) and (1=1)"
condition2 = "((2=3) or (1=1)) and (4=5)"

Above both condition gives me out-put True and False respectively.

More explanations :

condition1 work as ,

if ((2==2) or (3==1)) and (1==1):
      Return True
else:
      Return False

Output for condition1 : True

condition2 work as ,

if ((2==3) or (1==1)) and (4==5):
      Return True
else:
      Return False

Output for condition2 : True

Update :

Sorry Friends,

I have conditional string like above condition1 and condition2.

i want to make function when i parse condition as string and that function perform like if – else and return Boolean value

Please Help…

Thanks

Warning: Using eval is potentially dangerous and you should never eval untrusted input (for example any kind of user input).

In [1]: condition1 = "((2=2) or (3=1)) and (1=1)"
   ...: condition2 = "((2=3) or (1=1)) and (4=5)"
   ...: 

In [2]: eval(condition1.replace('=','=='))
Out[2]: True

In [3]: eval(condition2.replace('=','=='))
Out[3]: False
