Git - Keeping your code upto date!After cloning, we recommend creating a branch and doing your development on that branch:git checkout -b develop(assuming develop is the name of your branch)If the TAs push out an update to the assignment, you should co

for i in [10,20,30,40]: print(i)for i in range(5): print(f"square of {i} is {i**2}")i = 0while i<5: print(f"square of {i} is {i**2}") i += 1前两个输出都是square of 0 is 0square of 1 is 1square of 2 is 4square of 3 is 9square of 4 is 16some_arr

# The only way to modify tuple is to convert it to array/list and then back to tupletemp_list = list(some_tuple)temp_list[1] = 123some_tuple = tuple(temp_list)some_tuplelist()tuple()

array.pop()踢出并且输出array的最后一个元素

[-3:-1]是从-3开始，-1结束。包括-3，不包括-1.[-2：]是从-2开始，-1结束，包括-1，不包括0.

Shift + Enter - Run cell + select next cellAlt + Enter - Run cell + insert new cell belowHere are hotkeys you can use in command mode only.a - Insert cell aboveb - Insert cell belowShift + Up-Down Arrow key or Shift + mouse click cells - select multip

使用copy()函数import copya = [1,2]b = copy.copy(a)b.append(3)print(a)print(b)

把%%time放在cell的第一句，运行结束就会显示运行整个cell所用的时间。

numpy.ones(shape, dtype=None, order=‘C’, *, like=None)Return a new array of given shape and type, filled with ones.参数：shape：int or sequence of intsdtype：data-type, optionalThe desired data-type for the array, e.g., numpy.int8. Default is numpy.float64

创建新环境conda create --name ai_env python=3.7 -y删除环境conda remove -n ai_env --all重命名环境conda 其实没有重命名指令，实现重命名是通过 clone 完成的，分两步：先 clone 一份 new name 的环境conda create -n tf --clone ai_env删除 old name 的环境conda remove -n ai_env --all...

因为需要是conda --v而不是conda -v一个符号的差别

打开C:\Users\用户名\pip文件夹，只有一个pip.txt。解决方法：删除C:\Users\用户名里上次卸载没删干净的pip文件夹
