Value Types Vs Reference Types In C A Beginner Friendly Guide With @value("${this.property.value}") private string thisproperty; i would like to write unit tests for the validation methods inside this class, however, if possible i would like to do so without utilizing the properties file. @sollym internal or not, i'm still the one maintaining and using my code :p i would be annoyed if i got up a toenum in every intellisense menu, and like you say, since the only time you convert to an enum is from string or int, you can be pretty sure you'll only need those two methods. One common problem is that if you used a boolean mask to get a single value, but ended up with a value with an index (actually a series); e.g.: 0 1.2 name: btime, dtype: float64 you can use squeeze() to get the scalar value, i.e. If you look at the performance plots below, for most of the native pandas dtypes, value counts() is the most efficient (or equivalent to) option. 1 in particular, it's faster than both groupby.size and groupby.count for all dtypes. 2. it can make bins for histograms. you can not only count the frequency of each value, you can bin them in one go.

And if data in "age" column has similar records (i.e. many people are 25 years old, many others are 32 and so on), it causes confusion in aligning right count to each student. in order to avoid it, i joined the tables on student id as well. I know one way to check if a particular value is nan: >>> df.isnull().iloc[1,0] true but this checks the whole dataframe just to get one value, so i imagine it's wasteful. second option (not working) i thought below option, using iloc, would work as well, but it doesn't: >>> df.iloc[1,0] == np.nan false however if i check that value i get:.
