Python is a well-known programming language in many fields, including building websites, technical computing, machine learning and data analysis. However, Python does have faults that may prevent it from operating as intended. Defects must be found and fixed for Python code to function at its best. This essay offers a comparative examination of several Python code bug-finding methods. This study aims to assess these approaches' efficacy and efficiency in locating defects at the level of specific code lines. The relevance of bug identification and its effect on Python programs are briefly discussed in the first section of the article. Then it examines several methods for finding bugs, like testing procedures, static analysis and dynamic analysis. There is a detailed discussion of each approach's benefits, constraints and use cases.

Virtual reality technology has allowed people with special needs, specifically the blind and visually impaired, to access important information. This technology focused on immersing these groups in a three-dimensional environment and providing tools and applications that facilitate their daily lives by providing an immersive experience and tactile and auditory feedback through the application of virtual reality technology to bridge the gap of the problem of visual disability between the blind and visually impaired category. This article reviews the most important needs of people with visual impairment in various fields. This paper also discusses the most important assistive devices in the virtual reality environment, their functions, and applications. The paper also discussed the most important research that applied virtual reality technology to the blind and visually impaired. The determinants that will be taken into consideration in the future and appropriate solutions were highlighted to develop the benefit of virtual reality and serve this important category more.
