已有对文档进行操作的程序，如何对同一文件夹下所有文档进行此操作？

Question

原代码如下，之后是我写入该文档的操作。

 import numpy as np
import codecs
import time

if __name__ == '__main__':

    allCount = 0
    time = 0
    lastnum = -1
    lists = []
    linenum = 0

    #init numpy array
    with open('B48W21  .txt', 'r') as f:
        content = f.read()

    for x in content.splitlines():
        x = x.split(",")
        lists.append(x)

    a = np.array(lists)
    [rows, cols] = a.shape

    #open file
    fzt = open("zerotime.txt", "w")
    fot = open("onetime.txt", "w")

    fz = open("zero.txt", "w")
    fo = open("one.txt", "w")

    fzm = open("zeromeans.txt", "w")
    fom = open("onemeans.txt", "w")

我改后代码如下，但无法运行错误为：

File "", line 15
for ifile in file：
^
SyntaxError: invalid character in identifier

代码为

import numpy as np
import codecs
import time
import os
readfile='F:\\FCD\\实验2'
writefile='F:\\FCD\\实验副本2'
file=os.listdir(readfile)
if __name__ == '__main__':

    allCount = 0
    time = 0
    lastnum = -1
    lists = []
    linenum = 0
    for ifile in file：          
        #init numpy array
        with open(readfile+'\\'+ifile, 'r') as f:
            content = f.read()

        for x in content.splitlines():
            x = x.split(",")
            lists.append(x)

        a = np.array(lists)

        [rows, cols] = a.shape

        #open file
        fzt = open(writefile+'\\'+'zerotime'+ifile, "w")
        fot = open(writefile+'\\'+'onetime'+ifile, "w")

        fz = open(writefile+'\\'+'zero'+ifile, "w")
        fo = open(writefile+'\\'+'one'+ifile, "w")

        fzm = open(writefile+'\\'+'zeromean'+ifile, "w")
        fom = open(writefile+'\\'+'onemean'+ifile, "w")

 还是说我的思路有问题？对已有文档进行操作的程序，同一文件夹下所有文档进行此操作，不能仅仅修改读写文件，还有其他需要更改的地方？

强烈建议，模块化，不要一堆全写到main，既不利于阅读，也不便于定位和分析错误。参考一下本人写的（未实际运行，可能有简单的拼写错误）

import numpy as np
import codecs
import os

# Deal one file and write output files into output_dir
# Return True for success, False for fail.
def deal(file, output_dir):

    allCount = 0
    time = 0
    lastnum = -1
    lists = []
    linenum = 0

    # Do your work of one file

    if not os.path.isfile(file):
        print 'Error: ', file, 'is not a file'
        return False

    # Init numpy array
    with open(file, 'r') as f:
        content = f.read()

    for x in content.splitlines():
        x = x.split(',')
        lists.append(x)

    a = np.array(lists)
    [rows, cols] = a.shape

    # Open files and do something

    # Open files
    fzt = open(os.path.join(output_dir, 'zerotime.txt'), 'w')
    fot = open(os.path.join(output_dir, 'onetime.txt'), 'w')

    fz = open(os.path.join(output_dir, 'zero.txt'), 'w')
    fo = open(os.path.join(output_dir, 'one.txt'), 'w')

    fzm = open(os.path.join(output_dir, 'zeromeans.txt'), 'w')
    fom = open(os.path.join(output_dir, 'onemeans.txt'), 'w')

    # Do something

    # Close files
    fzt.close()
    fot.close()
    fz.close()
    fo.close()
    fzm.close()
    fom.close()

    return True

if __name == '__main__':

    if len(sys.argv) < 3:
        print 'Usage: ', sys.argv[0], ' <input_dir> <output_dir>'
        exit

    # Parse cmdline
    input_dir = sys.argv[1]
    output_dir = sys.argv[2]

    if not os.path.isdir(input_dir):
        print "Error: invalid input_dir: ", input_dir
        exit

    if not os.path.isdir(output_dir):
        print 'Warning: output_dir ', output_dir, ' doesn't exists, try to create it ...'
        os.mkdir(output_dir)
        if not os.path.isdir(output_dir):
            print 'Error: fail to create output_dir ', output_dir
            exit

    # Do works
    success_count = 0
    fail_count = 0
    for f in os.listdir(input_dir):
        # Skip dir
        if os.path.isdir(f):
            print 'Info: skip dir ', f
            continue

        # Deal file
        if deal(f, output_dir):
            success_count += 1
        else:
            fail_count += 1

    total_count = success_count + fail_count

    print total_count, 'file(s) in ', input_dir, 'have(has) been dealed'
    print 'Success: ', success_count
    print 'Fail: ', fail_count
