I've been working on a version of a script I found in
"Programming Python". The helpful users of this forum
gave me some advice to make the code less wordy. Here
is the code:
#!/usr/bin/python
import string
def find_longest_line(fileName):
line_list = [line.split() for line in open(fileName,
'r').readlines()]
numCols = max(len(cols) for cols in line_list)
#print numCols
return numCols
def summer(fileName):
length_longest_col = find_longest_line(fileName)
sums = [0] * length_longest_col
for line in line_list:
cols = string.split(line)
for i in range(len(cols)):
sums[i] = sums[i] + float(cols[i])
return sums
if __name__ == '__main__':
import sys
print summer(sys.argv[1])
#print find_longest_line(sys.argv[1])
The code opens a file called table.txt:
1 5 10 2 1.0
2 10 20 4 2.0 3
3 15 30 8 3 2 1
4 20 40 16 4.0
Then the script adds the columns in the file together.
However, when I run the script, I get a syntax error:
[EMAIL PROTECTED] ./text_proc 151> ./summer_v04.py
table.txt
File "./summer_v04.py", line 6
numCols = max(len(cols) for cols in line_list)
^
SyntaxError: invalid syntax
I can't figure out what the error is.
