Thank you all.
Here is the last piece of code that caused me so much troubles but now working
the way I wanted it:
fRawData = []
with open(fStagingFile2) as fStagingFile2FH:
fRawData = [line.strip() for line in
fStagingFile2FH.readlines()] # #### This is to read each element from
the file and chop off the end of line character
fNumberOfColumns = 7
fNumberOfRows = len(fRawData)/fNumberOfColumns
fRowID = 0
fParameters = []
for fRowID in range(0, len(fRawData), fNumberOfColumns):
fParameters.append(fRawData[fRowID:fRowID+fNumberOfColumns])
# #### This is to convert 1D array to 2D
# #### ... and down below section is an example of how to read each element
of the list
# #### and how to update it if I need so. That was also a problem before.
fRowID = 0
fColumnID = 0
for fRowID in range(fNumberOfRows):
for fColumnID in range(fNumberOfColumns):
if fColumnID == 0:
fParameters[fRowID][fColumnID] = "XXXX"
Message2Log("fParameters[" + str(fRowID) + "][" +
str(fColumnID) + "] = " + str(fParameters[fRowID][fColumnID]))
