If you are working with large tuples and you want to convert them into an array efficiently, you must usenumpy.fromiter()method. It avoids intermediate list creation, reducing memory overhead. importnumpyasnp#

int()The function accepts an argument representing a number and converts it to an integer. This argument can be a string, a floating point value, or an integer itself. The function considers the integer value or the part before the decimal point in the number and returns it. However, the...
Converting to List, Tuple, and Dictionary The`list()`, `tuple()`,and`dict()`functions convert values to a list, tuple, and dictionary, respectively. Here’s how you can use them: ```python print(list("hello"))# Output: ['h', 'e', 'l', 'l', 'o'] print(tuple([ 1,2,3]...

Some other variations, firstly create a Python tuple rather than a list: static PyObject * your_function_name(void) { std::vector<double> container = some_cpp_function_that_creates_a_vector(); return cpp_std_list_like_to_py_tuple(container); } Or work with a std::list rather than a...
You transfer a list in which you specify a function for data conversion for every column. If no data conversion is to be performed for a column, transfer the None object at the position of the column in question. cursor.setTypeTranslation ({'Date': sdb.dbapi.dateTuple,'Time': sdb.dbap...
