How I can multiply the fourth one from each row in the text file - canatilaa - Dec-25-2018
- 2, 1, 2, 3, **4**, 15, 14, 29, 64168.0, 1
2, 1, 2, 3, **6**, 15, 14, 29, 64168.0, 1
2, 1, 2, 3, **8**, 15, 14, 29, 64168.0, 1
I wanna multiply this item
elif menu == 4:
fin = open("data.txt", "r")
i = 0
n = 0
freeday = fin.read[i][9]
i = i + 1
print freeday
# 45 saatten fazla calısma yasası.......(n)
elif menu == 5:
fin = open("data.txt", "r")
for line in fin:
totalweekdayshour = [5]
totalweekendhour = [6]
if totalweekdayshour + totalweekendhour >= 45:
print ("workers must be work 45 h")
else:
print ("no problem")
fin.close`

Properly format and indent your code. It's much more readable. Not to mention python code will not work without proper indentation.
I formatted and indented your code below. But It's not clear what you are trying to do here.
elif menu == 4:
fin = open("data.txt", "r")
i = 0
n = 0
freeday = fin.read[i][9]
i = i + 1
print freeday
# 45 saatten fazla calısma yasası.......(n)
elif menu == 5:
fin = open("data.txt", "r")
for line in fin:
totalweekdayshour = [5]
totalweekendhour = [6]
if totalweekdayshour + totalweekendhour >= 45:
print ("workers must be work 45 h")
else:
print ("no problem")
fin.close()

As philia states, it's unclear as to what your intention is, however to access the various elements of your file,
split each line into a list, then it will be easy to work with. Example:
import os
# make sure we are in same directory as script:
os.chdir(os.path.abspath(os.path.dirname(__file__)))
with open('fin.txt', 'r') as fp:
linecount = 1
for line in fp:
line = line.strip().split(',')
print()
for n, item in enumerate(line):
print('item {} of line {} is equal to {}'.format(n, linecount, item))
linecount += 1will generate:Output:item 0 of line 1 is equal to - 2
item 1 of line 1 is equal to 1
item 2 of line 1 is equal to 2
item 3 of line 1 is equal to 3
item 4 of line 1 is equal to **4**
item 5 of line 1 is equal to 15
item 6 of line 1 is equal to 14
item 7 of line 1 is equal to 29
item 8 of line 1 is equal to 64168.0
item 9 of line 1 is equal to 1
item 0 of line 2 is equal to 2
item 1 of line 2 is equal to 1
item 2 of line 2 is equal to 2
item 3 of line 2 is equal to 3
item 4 of line 2 is equal to **6**
item 5 of line 2 is equal to 15
item 6 of line 2 is equal to 14
item 7 of line 2 is equal to 29
item 8 of line 2 is equal to 64168.0
item 9 of line 2 is equal to 1
item 0 of line 3 is equal to 2
item 1 of line 3 is equal to 1
item 2 of line 3 is equal to 2
item 3 of line 3 is equal to 3
item 4 of line 3 is equal to **8**
item 5 of line 3 is equal to 15
item 6 of line 3 is equal to 14
item 7 of line 3 is equal to 29
item 8 of line 3 is equal to 64168.0
item 9 of line 3 is equal to 1
