The line that's throwing the exception is
print begin + fixed_time +end
because begin
and end
are both lists and fixed_time
is a string. Whenever you take a slice of a list (that's the row[:6]
and row[:8]
parts), a list is returned. If you just want to print it out, you can do
print begin, fixed_time, end
and you won't get an error.
Corrected code:
I'm opening a new file for writing (I'm calling it 'final', but you can call it whatever you want), and I'm just writing everything to it with the one modification. It's easiest to just change the one element of the list that has the line (row[6] here
), and use '|'.join
to write a pipe character between each column.
import csv
with open('temp', 'r') as f, open('final', 'w') as fw:
reader = csv.reader(f, delimiter="|")
for row in reader:
# just change the element in the row to have the extra zeros
row[6] = '00:' + row[6]
# 'write the row back out, separated by | characters, and a new line.
fw.write('|'.join(row) + '\n')
