每次运行cod时返回没有输出的目录的终端

Question

我试图用python解决一个元组问题，我在终端上运行python代码，但是每次运行它时，它都会把我存储的文件夹带回来，没有任何输出。代码如下：

name = raw_input("Enter file:")
if len(name) < 1 : 
     name = "mbox-short.txt"
handle = open(name)
count = dict()
fh = handle.read()
for line in fh :
lines = line.rstrip()
if lines.startswith('From '):
        word = lines.split()``
        words = word[5] 
        wordss = words.split()
        wordsss = wordss[0]


        for letters in wordsss :
            count[letters] = wordsss.get(letter, 0) +1

        lst = list ()
        for k,v in count.items() :
                lst.append( (k,v) )
                lst.sort(k)
                print lst 

Answer 1

fh = handle.read()
for line in fh :
    lines = line.rstrip()

在这些行中，您读取所有文件内容并将其存储在fh中作为string。现在，当您在for line in fh中对它进行迭代时，您只得到line中的单个字符，因此line.rstrip()没有太大意义，if lines.startswith('From ')

Answer 2

name = raw_input("Enter file: ")
if len(name) < 1 : name = "mbox-short.txt"
handle = open(name)
hours = {}

# handle = open("mbox-short.txt")
for line in handle:
    if line.startswith('From '):
        hour = line.split()[-2].split(':')[0]
        if hour in hours:
            hours[hour] = hours[hour] + 1
        else:
            hours[hour] = 1

hours = sorted(hours.items())

for hour, count in hours:
    print hour, count

输出：
