利用Pycharm断点调试Python程序 1.代码 准备没有语法错误的Python程序: #!/usr/bin/pythonimport numpy as np class Network: def __init__(self,sizes): self.num_layers=len(sizes) self.sizes=sizes self.biases=[np.random.randn(y,1) for y in sizes[1:]] self.weights=[np.random.randn…
1.理解Pythonic概念 Pythonic Tim Peters 的 <The Zen of Python>相信学过 Python 的都耳熟能详,在交互式环境中输入import this可以查看,其实有意思的是这段 Python 之禅的源码: d = {} for c in (65, 97): for i in range(26): d[chr(i+c)] = chr((i+13) % 26 + c) print "".join([d.get(c, c) for c i…
