Question

Pylint在最后一行抱怨我在调用函数＆＃34; deletdcmfiles（）＆＃34;。＆＃34;最后的换行线缺失＆＃34;。我是python的新手，我不确定是什么触发了它？

以下是该计划的代码：

'''
This program will go through all Work subdirectorys in "D:\\Archvies" folder
and delete all DCM files older then three months.
'''
import os.path
import glob
import time

#Create a list of Work directorys in Archive folder
WORKDIR = glob.glob("D:\\Archives\\ASP*\\Work*")
#Variable holds three months of time in seconds
THREEMONTHSOLD = (time.time()) - (90 * 86400)

def deletdcmfiles():
    '''
    This function will go through all Work subdirectorys in "D:\\Archvies" folder
    and delete all DCM files older then three months.
    '''
    #Variable to keep counter of deleted files
    deleted_files = 0
    #Loop through each Work subdirectory and delete all .DCM files older then 3 months
    for mydir in enumerate(WORKDIR):
        #Store all directory files in a list
        dcmfiles = glob.glob(mydir[1] + "\\" + "*.dcm")
        #Compare Modified Date of each DCM file and delete if older then 3 Months
        for file in enumerate(dcmfiles):
            if os.path.getmtime(file[1]) < THREEMONTHSOLD:
                print("Deleted " + file[1] + " " + time.ctime(os.path.getmtime(file[1])))
                os.remove(file[1])
                deleted_files += 1
    print("Total Files Deleted :" + str(deleted_files))

#Run program
deletdcmfiles()

Answer 1

您需要在文件末尾添加一个空行。只需在最后一行的末尾添加另一个 ENTER ，你就没事了。

Answer 2

我刚遇到这个问题，发现 this answer 有类似的问题：

您至少需要一个换行符的原因是历史上有些如果文件结束并且最后一行上有文本，则工具会出现问题但文件末尾没有换行符。写得不好工具可能会错过最后部分行的处理，甚至更糟的是读取最后一行之后的随机内存（尽管这不太可能使用 Python 编写的工具发生使用编写的工具可能发生在 C）中）。

所以你必须确保有一个换行符终止最后一个非空白线。

Pylint给了我＆＃34;最后的新线缺失＆＃34;
