生成器表达式和列表推导式

#列表推导式
egg_list=[‘鸡蛋%s‘%i for i in range(10)]
print(egg_list)

egg_list = []
for i in range(10):
    egg_list.append(‘鸡蛋%s‘%i)
print(egg_list)

print([i*i for i in range(10)])

#生成器表达式
g = (i for i in range(10))
print(g)
for i in  g:
    print(i)

# # 括号不一样
# # 返回的值不一样 === 几乎不占用内存

老母鸡=(‘鸡蛋%s‘%i for i in range(10))   #生成器表达式
print(老母鸡)
for 蛋 in 老母鸡:
    print(蛋)
#
#平方
g = (i*i for i in range(10))
print(g.__next__())
print(g.__next__())
print(g.__next__())
