Disadvantages

Given such a lengthy description on how good is python as a programming language it is easy to be mistaken that python does not have any shortcomings. Some are listed:

• Since python is an interpreted language and it being built on C/C++ execution speed is slow. But the benefits/advantages dramatically outweigh this issue.

• Due to the above point python scripts are slower than other scripting languages.

• Database access layers are underdeveloped in python so server side applications involving extensive database use usually are not written in python.

• Rare run time errors due to the dynamic typing of variables.

• Errors are detected only when the buggy code is executed. In a production environment this could be a problem.

• Migration from python 2 to python 3 is a real pain.
