本文主要是關于numpy的一些基本運算的用法。
#!/usr/bin/env python
# _*_ coding: utf-8 _*_
import numpy as np
# Test 1
a = np.arange(4)
print a
# 直接賦值, a,b,c,d是同一個array
b = a
c = a
d = b
a[0] = 10
print b is a
print c is a
print d is a
# Test 1 result
[0 1 2 3]
True
True
True
# Test 2
# 深拷貝
b = a.copy()
b[0] = 12
print b is a
print a
print b
# Test 2 result
False
[10 1 2 3]
[12 1 2 3]
