When I tried append() it said I can't do that to a tuple. So not a list. But, I still get a float error when trying enumerate().
I'm trying simplify the code to less lines.

We assume that 'total' is defined as a list. How becomes a tuple?
I'm not sure. I borrowed the code for converting bytes to MB. There was no total=[] outside of it, but when I add it in, I still get the float error. Below, total and s are the same, but both give errors.
for i in xrange(len(filepaths)): filepaths[i] = (os.path.getsize(filepaths[i])) nums = filepaths[i] i = int(math.floor(math.log(nums, 1024))) p = math.pow(1024, i) s = round(nums/p, 2) total = s print total

You try to iterate a single value. Doesn't matter where you've got the code from
As and addition to what @wavic say,there are bad stuff in this code.
Never use range(len(something) ,not gone give up on this Also overwrite of the original filepaths,you are getting back byte size so do not call it filepaths.So look at this: # Bad import os filepaths = ['E:/1py_div/uni.txt', 'E:/1py_div/h.py', 'E:/1py_div/cloud9.txt'] for i in range(len(filepaths)): filepaths[i] = os.path.getsize(filepaths[i]) print(filepaths) # [22, 190, 42043] # Good import os filepaths = ['E:/1py_div/uni.txt', 'E:/1py_div/h.py', 'E:/1py_div/cloud9.txt'] file_byte_size = [] for index,item in enumerate(filepaths): file_byte_size.append(os.path.getsize(item)) print(file_byte_size) #[22, 190, 42043]Ahh come to think of this,it's easy to forget the the easiest solution. # Best import os filepaths = ['E:/1py_div/uni.txt', 'E:/1py_div/h.py', 'E:/1py_div/cloud9.txt'] file_byte_size = [] for item in filepaths: file_byte_size.append(os.path.getsize(item)) print(file_byte_size) #[22, 190, 42043]list comprehension is also okay. import os filepaths = ['E:/1py_div/uni.txt', 'E:/1py_div/h.py', 'E:/1py_div/cloud9.txt'] file_byte_size = [os.path.getsize(item) for item in filepaths] #[22, 190, 42043] |
