How to add characters at the end of the string in python?

Hello. Prompt how correctly to write script, to add at the end of specific lines of desired characters?

Code like this:
ARRAY = [['text1', 20], ['text2', 21]]
file_stat = open('text.csv', 'a+')
line_stat = file_stat.readlines()

for item in ARRAY:
 count = 'then the row count for the search item[0]'
// here I tried a few different options
 line_stat[item[1]] = line_stat[item[1]].rstrip('/n') + ',' + str(count) + '\n'

It is necessary in the line below the number specified in the array, at the end of the line add a comma and the number of rows, which turned out to calculate. But instead simply added a new line.
