How to let code find the file size and how to let user input segment size

[pohweihao]

f = open("centaur_1.mpg","rb")
#create a for loop and split file into 20 parts
buffer=f.read()  # readinto a large buffer to check its size
#f.close() #close the file
filesize=len(buffer)
print filesize
splitsize=int(filesize/segmentsize)
f.seek(0)  # reset to beginning of file
#smallfbuf=[]
for i in range(splitsize+1):
    filename="part"+str(i)+".mpg"
    f2= open(filename,"wb")
    buffer2 = f.read(splitsize)
    f2.write(buffer2)
    f2.close()
f.close()

from the above codes, how do i get the filesize and the user to input segmentsize

It looks like you can import os and then use the getsize() function to see the filesize:

[code=python]
import os
size = os.path.getsize ('centaur_1.mpg ')
print size
[/code]

So I got that from Googling "python get file size" and I would Google "python get user input" to allow the user to input the segment size.

Good luck!
