Hi all,
I was playing around with regular expressions and testing the simple
regular expression and its notworking for some reason.
I want to search "my-dog" at any of the place in a string and return the
index but its not working. I tried both in python 3.7.3 and 2.7.x. Can
anyone please help?

Hi, do you know what the '^' character does in your pattern?

I am using python 2.7.6 but I also tried on python 3.7.3.

Thanks David for your quick help. Appreciate it. When I tried on python
2.7.3 the same thing you did below I got the error after matches.group(0)
as follows:
AttributeError: NoneType object has no attribute 'group'.
I tried to check 'None' for no match for re.search as the documentation
says but

Thank you too for your answer. Ok, that means that in every case when exec
imports something it has its own global namespace,

Thanks David /Anthony for your help. I figured out the issue myself. I
dont need any ^, $ etc to the regex pattern and the plain string (for exp
my-dog) works fine. I am looking at creating a generic method so that
instead of passing my-dog i can pass my-cat or blah blah. I am thinking of

Hi,
I am no more able to start Python from Windows 7 environment.
I have the following message :
"The Application was unable to start correctly, (0xC142). Click OK to close
the application"
Do you have any idea where the problem is ?
Bests regards,
___
Christian Doa
No, I have to correct myself
x = 5
def f1():
exec("x = x + 1; print('f1 in:', x)")
return x
print('f1 out', f1())
results in the same, for me confusing, results.
f1 in: 6
f1 out 5

Inside a function exec assignments go to a *copy* of the local
First thank you for all the answers, very much appreciated.
I assume the root cause might be explained by the zen of python as well.
If the implementation is hard to explain, it's a bad idea.
Maybe I need to rethink my implementation :-)
