Amjed Abbas :

I'm new in python language. I tried to load a text file, to split columns and count for over limit values for many rows such as the following:

Box Type    Serial Nb   Sensor Type Line Name   Point Nb    Point Index Segd Code   Set Grid Easting    Set Grid Northing   Surface Elevation   Resistance(ohm) Noise (µV)  Leakage(Mo) Tilt (%)    Latest Update

these value for geophone abnormal specification 10 =Resistance(ohm),11=Noise (µV),12=Leakage(Mo) ,13=Tilt (%) , i work as qc for seismic survey exploration

My code is like the following:

myfile = open('aaa.txt','r')
myvar=(myfile.read())

rows = (myvar.split('\n'))
for i in range(1,len(rows)):
    if float(rows[i].split('   ')[10]) > 140:
        print (rows[i].split('   ')[10])

and I met this error:

Traceback (most recent call last):
     File "D:/Python/python/import_text2.py", line 11, in <module>
    if float(rows[i].split('   ')[10]) > 140:
IndexError: list index out of range

Can anyone help me please?

s.k :

A pure Python proposal

Your for loop is iterating of letters, I guess it's not what you want.

You can try this instead:

text_file = "aaa.txt"

with open(text_file,'r') as f:
    data = f.read()

threshold = 140

for row in data.split('\n'):
    # by default, the .split() method use the 
    # white space (any amount) as the separator.
    for word in row.split():
        try:
            if int(word) > threshold:
                print("{} is greater than {}".format(word, threshold))
        except:
            print("Cannot convert word to number.")
            pass

Here, we check the numerical value against the threshold.
If you want to check for the string length instead, you can modify the code on your own, it will be a good exercise, but in your data sample you don't have such cases.
