間隔輸出
print(value, ..., sep=' ', end='\n', file=sys.stdout)

objects -- 复数，表示可以一次输出多个对象。输出多个对象时，需要用 , 分隔。
sep -- 用来间隔多个对象，默认值是一个空格。
end -- 用来设定以什么结尾。默认值是换行符 \n，我们可以换成其他字符串。
file -- 要写入的文件对象。
flush -- 输出是否被缓存通常决定于 file，但如果 flush 关键字参数为 True，流会被强制刷新。

input()可以指定提示文字，使用者輸入的文字則以字串傳回（Python 2.7的輸入是使用raw_input()

while
----------------
while True:
#ch=0
n=int(input("請輸入一個數值："))

total=1
i=1

while (i<=n):

total *=i
i=i+1
print(total)
ch=int(input("請選擇：(1)繼續(2)停止"))
if (ch==2):
break
---------------------------------------
list
基本概念
常用函數(一)
1.元素相加 sum(串列名稱)
1.自計算
a=[12,56,99,21,52]

len1=len(a)
total=0

for i in range(len1-1,0-1,-1):
total +=a[i]

print("total:",total)
----------------------------------------
2.a=[12,56,99,21,52]
total=sum(a)
print("total:",total)
2.最大值max()

3.最小值 min()
4.正排序 sorted()
a=[12,56,99,21,52]

len1=len(a)
c=sorted(a)
for i in range(0,len1):

print(c[i])
5.逆排序 sorted(,reverse=True)
a=[12,56,99,21,52]

len1=len(a)
c=sorted(a,reverse=True)
for i in range(0,len1):
print(c[i])

-----------------------
6.判斷指定元素是在串列中
if 元素 in 串列名稱：
[程式區塊]
a=[10,20,30,40,60]
qp=30
x=False
if qp in a:
x=True
if x==True:
print("存在")
else:

print("不存在")
------------------------------
常用函數(一)
1.新增
物件.append(值)
mylist1=[]

mylist1.append("java")
mylist1.append("javascript")
mylist1.append("delphi")
mylist1.append("c++")
mylist1.append("jquery")

for i in mylist1:

print(i)
2.新增(插入)
物件.insert(索引位置，值)
mylist1=[]

mylist1.append("java")
mylist1.append("javascript")
mylist1.append("delphi")
mylist1.append("c++")
mylist1.append("jquery")
mylist1.insert(2,"php")

for i in mylist1:

print(i)
3.數量
物件.count(值)
data=["java","javascript","delphi","c++","jquery"]
qp="java"

c=data.count(qp)

print("[{0}]在串列中出現[{1}]次".format(qp,c))
4.索引位置
物件.index(值)
5.刪除：
物件.remove(值)
------------------------------

data=["java","javascript","delphi","c++","jquery"]
qp="javascript"

data.remove(qp)

waitKey(1) 中的数字代表等待按键输入之前的无效时间，单位为毫秒，在这个时间段内按键 ‘q’ 不会被记录，在这之后按键才会被记录，并在下一次进入if语段时起作用。也即经过无效时间以后，检测在上一次显示图像的时间段内按键 ‘q’ 有没有被按下，若无则跳出if语句段，捕获并显示下一帧图像。

若此参数置零，则代表在捕获并显示了一帧图像之后，程序将停留在if语句段中一直等待 ‘q’ 被键入。

cv2.waitKey(1) 与 0xFF（1111 1111）相与是因为cv2.waitKey(1) 的返回值不止8位，但是只有后8位实际有效，为避免产干扰，通过 ‘与’ 操作将其余位置0。
