The Key Differences: C Vs. Python

Python as well as C are both well-known programming languages, however they are hardly distinct. Learn about the differences between them and how to best use the two.

Millions of programmers depend upon the Python as well as C programming languages. They might have some certain similarities in their functionality, however they have fundamental differences.

Notably it is worth noting that the C programming language has a history an age older. It first came out in 1972, whereas Python first came out in. Since its release the programmers have embraced C due to its performance and adaptability. Python has gained popularity since the start into the new century, when it was just a decade old.

What Is the Python Programming Language?

Python is a top-level object-oriented programming language that has dynamic semantics. It comes with data structures that are built-in and useful to script. Python can also be used as a glue-language to connect software components. It’s also great to use for Rapid Action Development (RAD).

What Is the C Programming Language?

C is a procedural general-purpose programming language, which has gained immense popularity due to its ease of use and versatility. Programmers use C extensively to build software, operating systems and other complicated software.

The Key Differences Between the C and Python Programming Languages

Before diving into a thorough discussion, let’s take an overview of the major difference in C as well as Python:

  • C is a structured programming language in contrast, Python is an object-oriented programming language.
  • Python is a general-purpose programming language in contrast, C is mostly used to develop hardware-related applications as well as low-level programming.
  • C is an uncompiled language. Python is an interpreter language.
  • The execution of code is quicker in C than Python.
  • Python does not support pointer functions however pointers are supported in C.
  • C is a program with a small set of built-in functions , while Python’s library is more comprehensive.
  • In C it is mandatory to declare the type of variable however this isn’t required in Python.
  • C lets line-assignment however, it can cause error messages in Python.
  • Its syntax Python is simpler to comprehend than C’s.


C is a structured language as well as Python is an object-oriented programming language. Structured languages encourage applications built around functional blocks, whereas an object-oriented language is focused on objects and classes.

Memory Management

C is not as efficient in memory than Python. In contrast to the C programming language Python makes use of its memory assigning object references to variables. Additionally, it comes with an automated garbage collection system to recuperate memory that has been used up.

Variable Declaration

It is true that the C programming language creates variables for use in the future. But Python doesn’t support variable declarations. So, variables can’t be typed in Python. Variables can be used to refer to values of different kinds in the course of program execution.


Python is more slow than C due to the fact that Python is an interpreted language , while C is one that is compiled. Python transforms the source code to bytecode prior to execution. This means that Python always runs as the virtual machine.


C is an uncompiled language. It is possible to break down C compilation into phases. C compilation in pre-processing compiling linking, assembling, and pre-processing.

With Python the interpreter, it converts the source code files to bytes at the time of running.

Use of Pointers

Pointers are extensively utilized in the C as well as C++ language however Python does not have pointers. In C pointers, they are a type of variable that store the address of a variable. Python tends to separate memories from their users. Therefore, there is no need for pointers.


Debugging refers to identifying and reducing bugs within an application. In Python bugs, they occur at runtime , which stop the process of execution.

Data Structures

Data structures are the storage of data in a efficient and well-organized manner. There are many types of data structures using C such as Array linked list, Stack, Queue, etc.

Garbage Collection

C as well as C++ do not come with integrated garbage collections. Implementing a garbage collector for C is difficult and it would make the implementation slow in any case.

However, Python has a garbage collecter that is based on the thresholds of deallocation and allocation of objects. It removes any unneeded objects in order to free up memory.
