我正在寻找打印“蠕虫”从一套只有一次。有办法吗？

Question

这是到目前为止我的脚本，我们有一个文件要打开和排序。当我打印结果时，它会打印蠕虫的名称，就像每个蠕虫打印10-12次一样。有没有办法让它们只显示一次？如果您能提供任何帮助，我将不胜感激

仅当您处理完文件后才处理蠕虫列表

for eachLine in logFile:
    
    print(eachLine)
     
    fields = eachLine.split()
    for field in fields:
        if field.lower().find('worm')!= -1:
            uniqueWorms.append(field.lower())

# You're all done reading the file and collecting worms.
# NOW you can print the results
uniqueWorms = sorted(uniqueWorms)
for worm in uniqueWorms:
    print(worm)
