IndexError: list index out of range
Answered
Hi,
i want to read data from a text.file and store them in a dict variable but i got this error.
"TD.txt" looks like this:
o n 38
o m 38
o b 38
n p 9
m y 9
b q 42
y i 14
dict_of_neighbours = {}
with open('TD.txt') as f:
for line in f:
line_data=line.split()
if line_data[0] not in dict_of_neighbours:
_list = list()
_list.append([line_data[1],line_data[2]])
dict_of_neighbours[line_data[0]] = _list
else:
dict_of_neighbours[line_data[0]].append([line_data[1],
line_data[2]])
print(dict_of_neighbours)
---------------------------------------------------------------------------

Hi Geoffrey!
Most likely, there is an empty line in your text file. You would need to catch this edge case to avoid such errors.
Maybe it makes sense to look into some existing parsers, e.g., from the pandas module (Pandas: How to Read and Write Files – Real Python) to generate a DataFrame right away and have a more robust parser with more options and flexibility.
Cheers,
