How can I save NumPy arrays as part of a larger text file? I can write the arrays to a temp file using savetxt, and then read them back into a string, but this seems like redundant and inefficient coding (some of the arrays will be large). For example:
from numpy import * a=reshape(arange(12),(3,4)) b=reshape(arange(30),(6,5)) with open ('d.txt','w') as fh: fh.write('Some text\n') savetxt('tmp.txt', a, delimiter=',') with open ("tmp.txt", "r") as th: str=th.read() fh.write(str) fh.write('Some other text\n') savetxt('tmp.txt', b, delimiter=',') with open ("tmp.txt", "r") as th: str=th.read() fh.write(str)
