示例1: openscope

'''Opens a new (embedded) scope.
Args:
customlocals (dict): By default, the locals of the embedding scope
are visible in the new one. When this is not the desired
behaviour a dictionary of customized locals can be passed,
and those locals will become the only visible ones.

# 或者: from __builtin__ import set [as 别名]
def handle_set(self, span, name, expr):
'''Called when parser encounters a set directive.
It is a dummy method and should be overridden for actual use.

span (tuple of int): Start and end line of the directive.
name (str): Name of the variable.

to the variable.

Accepts unicode string and set it as environment variable 'name' containing
value 'value'.

# 或者: from __builtin__ import set [as 别名]
def unsetenv(name):
"""
Delete the environment variable 'name'.
"""

# thus `del os.environ[name]` has no effect onto the real
# environment. For this case we set the value to the empty string.

示例5: modified

# 或者: from __builtin__ import set [as 别名]

"""
Checks to see if the page has been modified since the version in the
requester's cache.
When you publish pages, you can include `Last-Modified` and `ETag`
with the date the page was last modified and an opaque token for
the particular version, respectively. When readers reload the page,
the browser sends along the modification date and etag value for
the version it has in its cache. If the page hasn't changed,
the server can just return `304 Not Modified` and not have to
send the whole page again.
This function takes the last-modified date `date` and the ETag `etag`
and checks the headers to see if they match. If they do, it returns
`True`, or otherwise it raises NotModified error. It also sets
`Last-Modified` and `ETag` output headers.
