Stepping Through Python Code for Debugging
In Java and C#, developers can seamlessly step through code to pinpoint potential issues. Does Python offer a similar debugging approach?
Using Python's Debugger: pdb
Python provides a built-in debugger called pdb that facilitates code tracing. By launching a Python program using python -m pdb myscript.py, you can access a set of commands for debugging:
- b: Set a breakpoint
- c: Continue debugging until reaching a breakpoint
- s: Step through the code
- n: Advance to the next line of code
- l: Display the source code in the current file
- u: Navigate up a stack frame
- d: Navigate down a stack frame
- p: Print the value of an expression
IDE Debuggers
If command-line debugging is not your preference, certain IDEs offer GUI-based debuggers. Pydev, Wing IDE, and PyCharm are notable options, with Wing offering a free "Personal" edition and PyCharm providing a free community edition.
The above is the detailed content of How Can I Step Through Python Code for Debugging?. For more information, please follow other related articles on the PHP Chinese website!
How do you create multi-dimensional arrays using NumPy?Apr 29, 2025 am 12:27 AMCreate multi-dimensional arrays with NumPy can be achieved through the following steps: 1) Use the numpy.array() function to create an array, such as np.array([[1,2,3],[4,5,6]]) to create a 2D array; 2) Use np.zeros(), np.ones(), np.random.random() and other functions to create an array filled with specific values; 3) Understand the shape and size properties of the array to ensure that the length of the sub-array is consistent and avoid errors; 4) Use the np.reshape() function to change the shape of the array; 5) Pay attention to memory usage to ensure that the code is clear and efficient.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
