You can use the PandasDataFrame.astype()function to convert a column from string/int to float, you can apply this on a specific column or on an entire DataFrame. To cast the data type to a 54-bit signed float,
You can use pandasDataFrame.astype()function to convert column to int(integer). You can apply this to a specific column or to an entire DataFrame. To cast the data type to a 64-bit signed integer, you can use numpy.int64, numpy.int_, int64, or int as param. To cast to a32-bit ...

Then, the astype() function is used on both the columns, converting column x to integer and column y to a complex number.Note that astype() will also generate an error when it encounters a value that it cannot convert to the specified datatype.The...

We can also directly incorporate a 2D NumPy array into a Pandas DataFrame. To do this, we have to convert a nested list to Pandas DataFrame and assign it to the existing DataFrame column with a column name. Here is a code snippet showing how to append a new NumPy array-based column dir...
