Troubleshoot "fatal error: Python.h: No such file or directory" in Building C Extensions

When attempting to build a shared library with a C extension, one may encounter the following error:

utilsmodule.c:1:20: fatal error: Python.h: No such file or directory
compilation terminated.
````

Addressing this error requires verifying the installation of Python header files and static libraries for development (dev). Depending on the operating system, the appropriate package manager should be employed for installation.

**Package Managers:**

* **apt (Ubuntu, Debian)**
  * `sudo apt-get install python-dev` (for python2.x)
  * `sudo apt-get install python3-dev` (for python3.x)

* **yum (CentOS, RHEL)**
  * `sudo yum install python-devel` (for python2.x)
  * `sudo yum install python3-devel` (for python3.x)

* **dnf (Fedora)**
  * `sudo dnf install python2-devel` (for python2.x)
  * `sudo dnf install python3-devel` (for python3.x)

* **zypper (openSUSE)**
  * `sudo zypper in python-devel` (for python2.x)
  * `sudo zypper in python3-devel` (for python3.x)

* **apk (Alpine)**
  * `sudo apk add python2-dev` (for python2.x)
  * `sudo apk add python3-dev` (for python3.x)

* **apt-cyg (Cygwin)**
  * `apt-cyg install python-devel` (for python2.x)
  * `apt-cyg install python3-devel` (for python3.x)

How to concatenate two lists in python 3?May 14, 2025 am 12:09 AM

In Python 3, two lists can be connected through a variety of methods: 1) Use operator, which is suitable for small lists, but is inefficient for large lists; 2) Use extend method, which is suitable for large lists, with high memory efficiency, but will modify the original list; 3) Use * operator, which is suitable for merging multiple lists, without modifying the original list; 4) Use itertools.chain, which is suitable for large data sets, with high memory efficiency.

Python concatenate list stringsMay 14, 2025 am 12:08 AM

Using the join() method is the most efficient way to connect strings from lists in Python. 1) Use the join() method to be efficient and easy to read. 2) The cycle uses operators inefficiently for large lists. 3) The combination of list comprehension and join() is suitable for scenarios that require conversion. 4) The reduce() method is suitable for other types of reductions, but is inefficient for string concatenation. The complete sentence ends.

Key features of Python include: 1. The syntax is concise and easy to understand, suitable for beginners; 2. Dynamic type system, improving development speed; 3. Rich standard library, supporting multiple tasks; 4. Strong community and ecosystem, providing extensive support; 5. Interpretation, suitable for scripting and rapid prototyping; 6. Multi-paradigm support, suitable for various programming styles.

Python: compiler or Interpreter?May 13, 2025 am 12:10 AM

Python is an interpreted language, but it also includes the compilation process. 1) Python code is first compiled into bytecode. 2) Bytecode is interpreted and executed by Python virtual machine. 3) This hybrid mechanism makes Python both flexible and efficient, but not as fast as a fully compiled language.
