syntax error when using command line in python

阅读更多关于 syntax error when using command line in python

问题 I am a beginner to python and am at the moment having trouble using the command line. I have a script test.py (which only contains print(\"Hello.\") ), and it is located in the map C:\\Python27. In my system variables, I have specified python to be C:\\Python27 (I have other versions of Python installed on my computer as well).

阅读更多关于 PHP expects T_PAAMAYIM_NEKUDOTAYIM?

问题 Does anyone have a T_PAAMAYIM_NEKUDOTAYIM ? 回答1: It’s the double colon operator :: (see list of parser tokens). 回答2: Google works wonders. It's Hebrew for "double colon". 回答3: It’s a name for the :: operator in PHP. It literally means "double colon". For some reason they named it in Hebrew.

Why does Eclipse complain about @Override on interface methods?

阅读更多关于 Why does Eclipse complain about @Override on interface methods?

问题 I have an existing project that uses @Override on methods that override interface methods, rather than superclass methods. I cannot alter this in code, but I would like Eclpse to stop complaining about the annotation, as I can still build with Maven. How would I go about disabling this error?

Python cannot handle numbers string starting with 0. Why?

阅读更多关于 Python cannot handle numbers string starting with 0. Why?

问题 I just executed the following program on my python interpreter: >>> def mylife(x): ... if x>0: ... print(x) ... else: ... print(-x) ... >>> mylife(01) File \"<stdin>\", line 1 mylife(01) ^ SyntaxError: invalid token >>> mylife(1) 1 >>> mylife(-1) 1 >>> mylife(0) 0 Now, I have seen this but as the link says, the 0 for octal does not work any more in python (i.e. does not work in python3). But does that not mean that the the behaviour for numbers starting with 0 should be interpreted properly?
