python的编程笔记-003

animals=['pig','dog','cat']
for A in animals:
	print("\n",A+". A dog would make a great pet!")
c="would make a great pet!"
print("\nAny of these ",animals[1].title(),c)#列表内元素打印！;两种不同的方式！


print("\n",animals[:2])#切片

for B in animals[0:2]:
	print("\n",B.title())#遍历切片

you_animals=animals[:]#复制列表
print(you_animals)

animals.append('wolf')
print(animals)
print(you_animals)
for C in animals:
	print("\n",C.title())
for D in animals:
	print("\n",D.lower())
#核实，只是复制，并没有改变原有的列表;第二部分，用for循环打印

print("\ni love:")
print(animals[:2])
print("\nShe love:")
print(animals[1])
print("\nHe love:")
print(animals[1:])

列表切片~
