Python循环

# 循环

# a = 1

# while a <= 10:

# a+=1

# print(a)

# else:

# print('98k')

# for循环是用来遍历/循环 序列或者集合，字典

# b = [['apple','banana','orange'],(1,2,3)]

# for x in b:

# for y in x:

# if y == 1:

# continue

# print(y,end = ' ')

# else:

# print('frult is gone')

# a = 0

# while a<=9:

# a+=1

# b = a

# print('a*b=',a*b)

乘法口诀

# for x in range(1,10):

# for y in range(1,x+1):

# print(x,'*',y,'= ',x*y)

#0代表的是开始数字，10代表的是从0开始位移10，,2是步长

 

获取偶数

# for x in range(0,10,2):

# print(x)

获取偶数倒序排列

# for x in range(10,0,-2):

# print(x)

 

 

获取数组中相邻的数字：

a = [1,2,3,4,5,6,7,8]

for i in range(0,len(a),2):

print(a[i])
