IndexError: list index out of range
Error message:

The code is as follows:
with open(“linux_Yue_01.txt”,”r”) as testFile:
testfileList = [splitFileNameAndLabel(filename = v) for v testFile.read().split(“\n”)]
The picture is as follows:

Error analysis:
The “IndexError: list index out of range” error typically occurs in two ways:
The first possible case:
List [index] Index is out of range
The second possibility:
The list is empty, with no elements
Listing [0] will report this error.
Typically, there is a problem with externally entered data, so it is usually processed once after readlines or read.
This avoids empty lines, insufficient fields, and type-casting errors.
Solutions:
For the first case, check the code through debugging, not much to say.
In the second case, there are two ways:
The first: check the data read in is there a problem, such as read in the TXT file whether there is a blank line and so on, but I more advocate the second solution, in the code error correction.
with open(“linux_Yue_01.txt”,”r”) as testFile:
testfileList = []
for v testFile.read().split(“\n”)
If not v.strip(): # string remove the space is not empty
continue
testfileList.extend([splitFileNameAndLabel(v)])
Note: [splitFileNameAndLabel(v)] is square again, otherwise it would not be a nested list in a list
