我正在使用扭曲的API并正在通过这个例子。 我插入了一个打印语句打印“在getdummydata”正确的缩进。代码如下:缩进错误python
from twisted.internet import reactor, defer
def getDummyData(x):
"""
This function is a dummy which simulates a delayed result and
returns a Deferred which will fire with that result. Don't try too
hard to understand this.
"""
print "in getdummydata"
d = defer.Deferred()
# simulate a delayed result by asking the reactor to fire the
# Deferred in 2 seconds time with the result x * 3
reactor.callLater(2, d.callback, x * 3)
return d
def printData(d):
"""
Data handling function to be added as a callback: handles the
data by printing the result
"""
print d
d = getDummyData(3)
d.addCallback(printData)
# manually set up the end of the process by asking the reactor to
# stop itself in 4 seconds time
reactor.callLater(4, reactor.stop)
# start up the Twisted reactor (event loop handler) manually
reactor.run()
但是当我运行的代码,它给下面的压痕错误:
File "C:\Python26\programs\twisttest.py", line 9
print "in getdummydata"
^
IndentationError: unexpected indent
请任何人都可以解释,为什么?
工作对我来说很好,正如预期的那样。确保你到处都有4个空格,并且没有标签。 – delnan 2010-08-25 19:30:04
