通过这个解释,我们将了解当 Python 程序显示类似NameError: name '<functionName>' is not Defined的错误时会出现什么情况,即使脚本中存在该函数。 我们还了解当我们使用拼写错误的变量或未导入的内置函数时会发生什么,以及如何在 Python 中避免这些错误。 避免在 Python 中声明之前调用函数 Python 中出现NameError: ...
>>> import re >>> test = 'Test match() function of regular expression.' >>> a = re.match(r'function',test) >>> print a None 这里注意上面两个例子中,我们分别在模式'Test'和'function'的前面加上了一个'r',这个'r'代表原始字符串(Raw String)。在Python中,原始字符串主要用来处理特殊字符...

The binary resulting from this step is not good for real-life workloads as it has profiling instructions embedded inside.After the instrumented interpreter is built, the Makefile will run a training workload. This is necessary in order to profile the interpreter's execution. Note also that any...
