1.for … in 循环
循环,遍历,迭代 都是指把容器中的数据一个一个获取出来
lst = [1,2,3,4,5]
i = 0
while i<len(lst):
print(lst[i])
i...遍历集合
container = {
"taibai","wusir","wuchao","bijiao"}
for i in container:
print(i)
3.遍历列表
''' Python...字符串有局限性,个数是2个,只能用2个变量收;
#a,b = {"a","b"} 集合有局限性,因为无序;
a,b ={
"a":1,"b":2}
print(a,b)
8.遍历等长的二级容器
''' Python...for i in range(5,10):
print(i)
3)range当中三个值得情况下
for i in range(1,15,2):
print(i)
4)range倒着打印
''' Python...= 1
while i<=9:
j = 1
while j <= i:
print("%s*%s=%2s"% (i,j,i*j),end=" ")
j += 1
print()
i +
