What is Python?
Python is a programming language that lets you work quickly and integrate systems more effectively.
It is an interpreted, object-oriented, high-level programming language with dynamic semantics. Its high-level built in data structures, combined with dynamic typing and dynamic binding, make it very attractive for Rapid Application Development, as well as for use as a scripting or glue language to connect existing components together. Python’s simple, easy to learn syntax emphasizes readability and therefore reduces the cost of program maintenance. Python supports modules and packages, which encourages program modularity and code reuse. The Python interpreter and the extensive standard library are available in source or binary form without charge for all major platforms, and can be freely distributed.[/vc_column_text][vc_column_text]Often, developers become hopelessly enamored with Python in light of the expanded profitability it gives. Since there is no compilation step, the alter test-investigate cycle is extraordinarily quick. Troubleshooting Python projects is simple: a bug or awful info will never bring about a segmentation fault. Rather, when the interpreter finds a mistake, it raises an exemption. At the point when the program doesn’t get the exemption, the translator prints a stack trace. A source level debugger permits assessment of neighborhood and worldwide variables, assessment of discretionary expressions, setting breakpoints, venturing through the code a line at once, et cetera. The debugger is composed in Python itself, vouching for Python’s contemplative power. Then again, frequently the snappiest approach to investigate a program is to add a couple print explanations to the source: the quick alter test-troubleshoot cycle makes this straightforward approach extremely compelling.
