I try this:
f1 = open("f1",'r')
f2 = open("f2", 'r')
if (difflib.context_diff(f1.readlines(), f2.readlines()).len()
== 0):
But I get this error:
Traceback (most recent call last):
File "./scripts/regressionTest.py", line 72, in ?
runTest(savedPagesDirectory, outputDir, expectedResultDir,
failedDir);
File "./scripts/regressionTest.py", line 60, in runTest
getSnapShot(fileName, testNo, outputDir, expectedResultDir,
failedDir)
File "./scripts/regressionTest.py", line 30, in getSnapShot
if (difflib.context_diff(f1.readlines(), f2.readlines()).len() ==
0):
# no difference
else:
# files are different
AttributeError: 'generator' object has no attribute 'len'
Can you please help?
