The above code creates a pandas DataFrame 'df' with three columns - 'col1', 'col2', and 'col3'. The code then uses the 'argmax()' function to find the index of the maximum value in each column. Therefore - The first 'print' statement returns the index of the row that has the ...
TheDataFrame.notnamethod detects non-missing values. main.py first_non_nan=df.notna().idxmax()print(first_non_nan)last_non_nan=df.notna()[::-1].idxmax()print(last_non_nan) TheDataFrame.idxmaxmethod returns the index of the first occurrence of the max value over the requested axis. ...

The function in the numpy modulewhere()is used to return an array containing the indices of the elements that satisfy some condition. The condition is specified in the function. We can use this to find the first index of a specific value in an array as shown below. ...
We used the max() function to get the max starting value of the two ranges. main.py def find_range_overlap(a, b): return list(range(max(a[0], b[0]), min(a[-1], b[-1]) + 1)) The max() function returns the largest item in an iterable or the largest of two or more ...

The fit method first checks if the number of columns in the dataframe and the schema are equal. If not, it creates an exception. Finally, the fit method displays a table of exceptions it found in your data against the given schema.
