Python的pprint模块中使用的格式化可以按照一种格式正确的显示数据, 这种格式即可被解析器解析, 又很易读. 输出保存在一个单行内, 但如果有必要, 在分割多行数据时也可使用缩进表示.
import sysimport pprintpprint.pprint(sys.path)
运行结果：
['', '/usr/local/lib/python27.zip', '/usr/local/lib/python2.7', '/usr/local/lib/python2.7/plat-linux2', '/usr/local/lib/python2.7/lib-tk', '/usr/local/lib/python2.7/lib-old', '/usr/local/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/site-packages']
如果仅仅想获得数据而不是输出数据也可以用pformat
import sysimport pprintstr = pprint.pformat(sys.path)print str
运行结果：
['', '/usr/local/lib/python27.zip', '/usr/local/lib/python2.7', '/usr/local/lib/python2.7/plat-linux2', '/usr/local/lib/python2.7/lib-tk', '/usr/local/lib/python2.7/lib-old', '/usr/local/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/site-packages']
运行结果是一样的~~
