我有一个名为sample_ips.txt的文本文件,其中包含一些随机IP地址,如下所示: -
182.0.0.15
182.0.0.16
182.0.0.17
我提供了一个IP地址作为输入来检查文本文件中是否存在IP,它打印为true,否则为false。
这是我的代码段: -
ip_input = str(input("Enter IP:"))
ip = open("sample_ips", "r")
data = ip.readlines()
for ips in data:
ips = ips.strip("\n")
if ip_input in ips:
print "true"
else:
print "false"
抛出语法错误
File "<string>", line 1
182.0.0.15
^
SyntaxError: invalid sytanx
我认为尽管我在代码中将其声明为字符串,但它无法将输入作为字符串。有帮助吗? 感谢

input_ip = raw_input("Enter IP:") # In python 2.x. If you use input() then type your inputs as string (>>Enter IP:"182.0.0.15")
#input_ip = input("Enter IP:") for python 3.x
with open("ip.txt", "r") as ip:
data = ip.readlines()
for ips in data:
ips = ips.strip("\n")
if input_ip in ips:
print ("true")
else:
print ("false")

嗯,这很有效:
input = raw_input("Enter IP:")
ip = open("sample_ips.txt", "r")
data = ip.readlines()
for ips in data:
ips = ips.strip("\n")
if input in ips:
print "true"
else:
print "false"

Python3版
input = input("Enter IP:")
ip = open("sample_ips.txt", "r")
data = ip.readlines()
for ips in data:
ips = ips.strip("\n")
if input in ips:
print ("true")
else:
print ("false")
