[python] Read file as a list of tuples, 파일읽어서 튜플 만들기

Yes Cyber solution is best.

For beginners

1. Read file in Read mode.
2. Iterate lines by readlines() or readline()
3. Use split(",") method to split line by '
4. Use float to convert string value to float. OR We can use eval() also.
5. Use list append() method to append tuple to list.
6. Use try except to prevent code from break.

My text file is:

-34.968398,-6.487265
-34.969448,-6.488250
-34.967364,-6.492370
-34.965735,-6.582322


Code:

p = "/home/vivek/Desktop/test.txt"
result = []
with open(p, "rb") as fp:
    for i in fp.readlines():
        tmp = i.split(",")
        try:
            result.append((float(tmp[0]), float(tmp[1])))
            #result.append((eval(tmp[0]), eval(tmp[1])))
        except:pass

print result


Output:

$ python test.py 
[(-34.968398, -6.487265), (-34.969448, -6.48825), (-34.967364, -6.49237), (-34.965735, -6.582322)]
