# 使用for打印出一个List
print(‘today to learn the ‘)
names = [‘aa‘, ‘bb‘, ‘cc‘]
for i in names:
    print(i)

# 使用range来生成1,2,3,4,5
for value in range(1, 5):
    print(value)

# 使用range来生成1-15的奇数
number = list(range(1, 15, 2))
print(number)

# 使用range来生成1-10的平方数
squares = []
for i in range(1,11):
    squares.append(i**2)
print(squares)

# 使用range来生成1-10的平方数

squares2 = [i**2 for i in range(1, 11)]

print(squares2)

# practice

for i in range(1,21):
    print(i)

list2 = list(range(1, 21, 2))
for i in list2:
    print(i)

# 生成1-30中可以除以3的整数
list3= list(range(1, 31))
b = []
for i in list3:
    if(i%3==0):
        b.append(i)
    else:
        continue
print(b)

# 使用range来生成1-10的立方数

list4 = [i**3 for i in range(1,11)]
print(list4)
