Question

文件中的行下面。

god is great
god is excellent
i am excellent
you are not good
I am also bad
world is awesome

在所有这些行中，我需要填充下面三行，但这些行不应与“好”和“很棒”之类的词匹配。

这是代码。但这不能按预期工作。

f = open('test2.txt')
lines = [line for line in f.readlines() if line.strip()] 
total_lines=len(lines)

index1=[0,1,2]
all_index=list(range(0,total_lines))

list3 = [i for i in all_index if not i in index1] ## Capturing Index (3,4,5)

words_not_require=['good','awesome']  ## Lines matching these words not required in final list

for j in list3:
    print (''.join(i for i in lines[j] if i not in words_not_require))

Answer 1

keeplist = []
words_not_require=['good','awesome']
with open('test2.txt', 'r') as f:
    lines = f.readlines()
    for line in lines:
        line = line.strip()
        if not any(word in line for word in words_not_require):
            keeplist.append(line)

print (keeplist)
#Output:
#['god is great', 'god is excellent', 'i am excellent', 'I am also bad']

这会过滤掉test2.txt文件中在words_not_require中带有单词的行

keeplist = []
words_not_require=['good','awesome']
with open('test2.txt', 'r+') as f:
    lines = f.readlines()
    for line in lines[3:]: #this gives you lines 4 onwards
        line = line.strip()
        for word in words_not_require:
            line = line.replace(word, '')
        keeplist.append(line)

print (keeplist)
#Output:
#['you are not ', 'I am also bad', 'world is ']

如果您只想替换切片行中的words_not_require中的单词，请使用上面的代码。

此外，使用with打开文件，这样您就可以不必调用f.close()。 with将唤起dunder方法__exit__来帮助关闭文件

Answer 2

我相信您想将最后两行更改为：

`import logging.Logger.info

class Project(name: String, daysToComplete: Int)

class Test {
  val project1 = new Project("TPS Reports", 1)
  val project2 = new Project("Website redesign", 5)
  info("Created projects")  // Prints "INFO: Created projects"
}`

输出：

for j in list3:
    print(' '.join([word for word in lines[j].split() if word not in words_not_require]))

匹配单词行不在最终列表中考虑，而是基于索引值
