I use python 2.5, i like to replace certain variables in a txt file and write the complete data into new file.
i wrote a program to do the above,
from scipy import * import numpy from numpy import asarray from string import Template def Dat(Par): Par = numpy.asarray(Par) Par = a1 Par = a2 Par = a3 Par = a4 sTemplate=Template(open('/home/av/W/python/data.txt', 'r').read()).safe_substitute(Par) open('/home/av/W/python/data_new.txt' ,'w').write(sTemplate) Init = numpy.asarray [(10.0, 200.0, 500.0, 10.0)] Dat(Init)
when i executed the above
*i obtained the error
'TypeError: 'function' object is unsubscriptable'
'data.txt' is a text file, i have placed $a1, $a2, $a3, $a4, i need to replace $a1 $a2 $a3 $a4 by 10.0 200.0 500.0 10.0
My constraints are i need to pass the values only by array like Init = numpy.asarray [(10.0, 200.0, 500.0, 10.0)]
please help me.
is this error due to python 2.5 version? or any mistakes in program
The error is here:
which was probably meant to be
(note the swapped braces/parens). Since python found a "
[" after "
asarray" (which is a function), it throws an error, because you cannot subscribe (i.e. do something like
x) a function.
