read file problem

[Ernesto]

I'm just want to read in the contents of a (text) file. The text file
is filled with semiColon delimited floating point strings...

0.456;1.265;99.742;...

For some reason, I can't get the contents back when I call file.read()
Here's my code.

filePath = "C:\\folder\\myFile.txt
fileHandle = open(filePath, 'r').read();
print fileHandle.read()

# This prints nothing when it should print the above values.... Thanks
for the help

Try adding a 'print fileHandle' in there...

That line should be :

fileHandle = open(filePath, 'r')

The '.read()' part returns the full file... so further reads have no
effect.

All the best,

Ernesto:

fileHandle = open(filePath, 'r').read();

^^^^^^^^
Remove this:

open() returns the filehandle, open().read() returns the data read from
the filehandle.

Thanks to all.

if you want the numbers you can combine it into one-liner

nums = file(r"C:\folder\myFile.txt").read().split(";")

the numbers are in string representation in the list
you can no do

nums = [float(num) for num in nums]
