Resolving Python Package Installation Error: [SSL: TLSV1_ALERT_PROTOCOL_VERSION]
When attempting to install a Python library using pip, you may encounter an SSL error: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version. This error arises due to recent TLS deprecation for pip.
Solution:
To resolve this issue, upgrade pip to the latest version:
curl https://bootstrap.pypa.io/get-pip.py | python
Note: If you are using pip within a virtual environment, you need to upgrade pip within that environment.
Step-by-Step for PyCharm (virtualenv) Users:
- Run the virtual environment shell.
-
Execute the pip upgrade command:
curl https://bootstrap.pypa.io/get-pip.py | python
- Restart PyCharm.
- Verify that your Python interpreter in PyCharm's Preferences has been updated.
Additional Information:
Pip requires TLS support for secure downloads. Since Python.org sites have discontinued support for TLS versions 1.0 and 1.1, you must upgrade pip to use TLS versions 1.2 or higher.

Python lists can store different types of data. The example list contains integers, strings, floating point numbers, booleans, nested lists, and dictionaries. List flexibility is valuable in data processing and prototyping, but it needs to be used with caution to ensure the readability and maintainability of the code.
