Speed Limitations   Speed has always been the key focus of a programmer and will always be an essential criterion to work on. Python is an interpreted languages and therefore is slower in execution than other languages like C/C++ , java , or newer languages like Juila. For Python, the execution takes place with the help of an interpreter instead of a compiler , and that causes it to slow down. Memory Consumption App development and computing programs are memory-intensive tasks , and due to high memory consumption by Python , it isn't considered a right choice for memory-intensive jobs. Python's high memory consumption is also due to the flexibility of data types. Difficult To Blend In Python is a very addictive language , and Python lovers get so accustomed with its features and extensive libraries that become difficult for them to learn or work on  other programming language.
