Python-Demo

获取Error.log文件内出现过的所有的ip

f = open("error.log")
a = set()
for line in f:
    line = f.readline()
    if line.strip() == '':
        continue
    if line and 'client' in line:
        ip = line.split(",")
        ip = ip[1]
        ip = ip.split(":")
        ip = ip[1].strip()
        a.add(ip)
f.close()

z = open("1.py.res.log", 'w')
for ip in a:
    z.write(ip)
    z.write("\n")
z.close()

获取Error.log文件内出现过的所有的ip以及每个ip出现了多少次

f = open("error.log")
a = dict()

for lines in f:
    line = lines.strip()
    if line and 'client' in line:
        ip = line.split(",")
        ip = ip[1]
        ip = ip.split(":")
        ip = ip[1].strip()
        if ip in a:
            a[ip] = a[ip] + 1
        else:
            a[ip] = 
f.close()

z = open("2.py.res.log", 'w')
bb = sorted(a.items(), key=lambda item: item[1], reverse=True)

# 遍历字典列表
for key, values in bb:
    z.write("%s ==== %s \n" % (key, values))
z.close()
