python截取关键字后的字符串_使用正则表达式获取python中特定字符串之后的所有内容...

如果要使用正则表达式，请使用re.findall：re.findall('(?<=com/).*$', "/thedubaimall")

# ['thedubaimall']

一些速度测试有@DeepSpace的建议：%timeit re.findall('(?<=com/).*$', "/thedubaimall")

# The slowest run took 7.57 times longer than the fastest. This could mean that an intermediate result is being cached.

# 1000000 loops, best of 3: 1.29 µs per loop

%timeit re.findall('com/(.*)', "/thedubaimall")

# The slowest run took 6.48 times longer than the fastest. This could mean that an intermediate result is being cached.

# 1000000 loops, best of 3: 992 ns per loop

%timeit "/thedubaimall".partition(".com/")[2]

# The slowest run took 7.87 times longer than the fastest. This could mean that an intermediate result is being cached.

# 1000000 loops, best of 3: 204 ns per loop

看起来，@DeepSpace的建议快了一点，@Kevin的回答快多了。
