Python 3.7.2

Warning: Python 3.7.2 reached end-of-life on 2023-06-27. It is no longer supported and does not receive security updates. We recommend upgrading to the latest Python release.
Note: Python 3.7.2 has been superseded by Python 3.7.17.

Release date: Dec. 24, 2018

Note: The release you are looking at is a bugfix release for the legacy 3.7 series which has now reached end-of-life and is no longer supported. See the downloads page for currently supported versions of Python. The final source-only security fix release for 3.7 was 3.7.17.

Among the major new features in Python 3.7 are:

  • PEP 539, new C API for thread-local storage
  • PEP 545, Python documentation translations
  • New documentation translations: Japanese, French, and Korean.
  • PEP 552, Deterministic pyc files
  • PEP 553, Built-in breakpoint()
  • PEP 557, Data Classes
  • PEP 560, Core support for typing module and generic types
  • PEP 562, Customization of access to module attributes
  • PEP 563, Postponed evaluation of annotations
  • PEP 564, Time functions with nanosecond resolution
  • PEP 565, Improved DeprecationWarning handling
  • PEP 567, Context Variables
  • Avoiding the use of ASCII as a default text encoding (PEP 538, legacy C locale coercion and PEP 540, forced UTF-8 runtime mode)
  • The insertion-order preservation nature of dict objects is now an official part of the Python language spec.
  • Notable performance improvements in many areas.

Windows users

  • The binaries for AMD64 will also work on processors that implement the Intel 64 architecture. (Also known as the "x64" architecture, and formerly known as both "EM64T" and "x86-64".)
  • There are now "web-based" installers for Windows platforms; the installer will download the needed software components at installation time.
  • There are redistributable zip files containing the Windows builds, making it easy to redistribute Python as part of another software package. Please see the documentation regarding Embedded Distribution for more information.
  • UPDATED 2019-01-09: An issue was discovered in the embeddable packages for Windows and updated download files have been provided for the Windows x86-64 embeddable zip file and the Windows x86 embeddable zip file and their GPG signatures. No other download was affected. See https://bugs.python.org/issue35596 for more information.

macOS users

  • For Python 3.7 releases, we provide two binary installer options for download. The default variant is 64-bit-only and works on macOS 10.9 (Mavericks) and later systems. We also continue to provide a 64-bit/32-bit variant that works on all versions of macOS from 10.6 (Snow Leopard) on. Both variants now come with batteries-included versions oF Tcl/Tk 8.6 for users of IDLE and other tkinter-based GUI applications; third-party and system versions of Tcl/Tk are no longer used. Consider using the newer 10.9 64-bit-only installer variant, unless you are building Python applications that also need to work on older macOS systems.
  • Both python.org installer variants include private copies of OpenSSL 1.1.0. Please carefully read the Important Information displayed during installation for information about SSL/TLS certificate validation and the Install Certificates.command.
