Below is the code I have created. I want the code to read data from a file called SIL633.txt and then output that data into another file called test.txt. below is my code:</div>
<div><br></div><div><div>#! /usr/bin/env python</div><div># Read NRG Text File</div><div>def readNRGtxt():</div><div><span style="white-space:pre-wrap"> </span>import numpy as np</div><div><span style="white-space:pre-wrap"> </span>f1 = open('SIL633_original.txt','r')</div>
<div><span style="white-space:pre-wrap"> </span>data = np.genfromtxt(f1,delimiter='\t',skip_header=141)</div><div><span style="white-space:pre-wrap"> </span>f1.close</div><div><span style="white-space:pre-wrap"> </span>f2 = open('test.txt','w')</div>
<div><span style="white-space:pre-wrap"> </span>np.savetxt(f2,data,fmt='%6.2f',delimiter='\t')</div><div><span style="white-space:pre-wrap"> </span>f2.close</div></div><div>
<br></div><div>I'm running this on mac 10.5.8. When I run this script from the command line, there is no file output. However, if I remove the "def" statement in the script and run again from the command line, a test.txt file is output. I guess I'm trying to understand why using the def statement changes how the script operates and since it does, how do I correct this code so it runs from the command line with the def statement.</div>
<div><br></div><div>thanks for any help -- jeremy</div>
