I am new in Python and I was curious if I can do something like this: Let's say that I have a list of tuples and one variable like this:

list = [(123,"a"),(125,"b")]
variable = (123,"c")

Is it possible to search for the first element of the variable in the list like this?

if variable[0] in list[0]:

Yes. But I do not know if it has the effect you want. Now you have bascially written `123 in (123,"a")` which is correct. But if this was the second tuple, it would fail. – Willem Van Onsem Oct 19 '17 at 20:37
What problem did you have when you tried this? – Prune Oct 19 '17 at 20:37
I've given you two duplicates that cover both use-cases; finding all matching tuples, and testing all or any of the elements match. – Martijn Pieters Oct 19 '17 at 20:37
For your case, `any(item[0] == variable[0] for item in list)`. – Martijn Pieters Oct 19 '17 at 20:38
