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

code

test_python_170323d.py
atuple = ((3, 1, 4), (1, 5, 9), (2, 6, 5))
print(atuple)

# 1 
res = [ flatten for inner in atuple for flatten in inner ]
res = tuple(res)
print(res)

# 2
res = ()
for rows in atuple:
    res = res + rows

print(res)
結果
$ python test_python_170323d.py 
((3, 1, 4), (1, 5, 9), (2, 6, 5))
(3, 1, 4, 1, 5, 9, 2, 6, 5)
(3, 1, 4, 1, 5, 9, 2, 6, 5)

方法1はコードを読んでからの理解時間(Readable codeでのTime-till-understanding)が長い。

当面、方法2の実装を使いそう。
