先上代码再解释：

#!/usr/bin/python# -*- coding: UTF-8 -*- s = "target_link_libraries(qtinfra_canvas \n   PUBLIC Qt4::QtGui    \nPRIVATE infra common qtinfra_util)"s1 = s[s.index('(')+1:s.index(')')] s2 = s1.split(" ")s3 = map(lambda s: s.strip(), s2)s4 = filter(None, s3) print s1print s2print s3print s4'''Output:qtinfra_canvas   PUBLIC Qt4::QtGuiPRIVATE infra common qtinfra_util['qtinfra_canvas', '\n', '', '', 'PUBLIC', 'Qt4::QtGui', '', '', '', '\nPRIVATE', 'infra', 'c['qtinfra_canvas', '', '', '', 'PUBLIC', 'Qt4::QtGui', '', '', '', 'PRIVATE', 'infra', 'commo['qtinfra_canvas', 'PUBLIC', 'Qt4::QtGui', 'PRIVATE', 'infra', 'common', 'qtinfra_util']'''

去除字符串里面的\n：str.strip()

去除list里面的\n（不减少元素数量）：newStr = map(lambda s: s.strip(), oldStr)

去除list里面为空的元素：newStr = filter(None, oldStr)

切分字符串（可以结合正则表达式来做：re模块（需import re）里面的re.split()）：

用空格：s2 = s1.split(" ")

用逗号：s2 = s1.split(",")
