Python > 3.14_1592_6535_8972 > PEP515 (Python v3.6以降可能な書き方)

動作環境
Xeon E5-2620 v4 (8コア) x 2
32GB RAM
CentOS 6.8 (64bit)
openmpi-1.8.x86_64 とその-devel
mpich.x86_64 3.1-5.el6とその-devel
gcc version 4.4.7 (とgfortran)
NCAR Command Language Version 6.3.0
WRF v3.7.1を使用。
Python 2.6.6 (r266:84292, Aug 18 2016, 15:13:37) 
Python 3.6.0 on virtualenv

Python 3.6以降で可能になった書き方。

pi = 3.14_1592_6535
print(pi)

このあたりは、Fortran77では("_")の代わりに(" ")では可能でFortran90はダメや、Javaだと可能という情報のやり取りはしたことがあります。

Pythonでも使えるようになっていたのですね。

有効桁数の長い数字を間違いなく扱いたい時などには有効だと思います。
