Thread: Searching through a list of dictionaries with a condition.
Post: RE: Searching through a list of dictionaries with ...
| My bad, I never properly removed the newline characters as I am using a real dataset (a file), as opposed to a constructed one as in the example I gave. Thanks for your patience and guidance. |

Thread: Searching through a list of dictionaries with a condition.
Post: RE: Searching through a list of dictionaries with ...
| Yeah, but the question is, if every dictionary in the list has the same keys-values (structure), can one exclusively access and retrieve the value of the key you're interested in and only that key. |

Thread: poosible bug
Post: RE: poosible bug
| I don't think it's a bug. It's just unique to python3.6.
You could use round:
a="1.1"
b="2.2"
# Here the number of decimal places is the 2nd argument.
x=round(float(a)+float(b), 2)
print(x) |

| Thanks, I like the last solution best. Didn't know about csv reader so that will be useful in the future. And I would never have looked up set(). I have to say it's much simpler than Perl. |
