Transform from squinting at error messages to systematically hunting down bugs. Learn how Python’s built-in debugger (PDB) can reduce your debugging time by 60-80% and help you write more reliable code.

I will explain the difference between the sep and end parameters in Python print statement. These parameters are useful for formatting the output of your print statements and making them more readable and customizable. The sep parameter specifies the separator between the values that are printed. By default, it is a single space character. For Continue reading

We’ll explore how to calculate bond prices using Python, covering both regular coupon bonds and zero-coupon bonds. Bonds are a fundamental component in finance, and understanding how to compute their prices is essential for investors and financial analysts.

Master multiple techniques for converting integers to binary in Python. Learn which method is fastest, most readable, and best for your specific use case with performance benchmarks. ⚡ Quick Answer: Use bin(42) for simple conversion (returns ‘0b101010’). Use format(42, ‘b’) to remove the ‘0b’ prefix. Use format(42, ’08b’) for fixed-width binary with leading zeros.

In Python, you can find the length of an array using various methods. The most commonly used method is the built-in len function, which returns the number of elements in an array.

The error “TypeError: only integer scalar arrays can be converted to a scalar index” occurs when you try to use a non-integer value (like a float, boolean, or another array) as an index to access an element of a NumPy array or a standard Python list. Indexing must be done with integers or slices.

Encountering a TypeError: unsupported operand type(s) for + in Python is a common issue, especially for beginners. This error occurs when you attempt to use the addition operator (+) with data types that are not compatible for addition. This tutorial will explain the common scenarios that cause this error and provide clear solutions.
