基本程式設計(二)

height = eval(input('enter your heigth:')) 
weigth = eval(input('enter your weigth:'))

bmi = weigth/((height/100)**2)
print('your is', bmi ,'!!!')

tempC = eval(input('input Celsius temperature：'))

tempF = tempC * (9/5) + 32
print('Celsius temperature', tempC , '= tempF', tempF)

chapter-7

基本程式設計(二)

intA = 5
intB = 3

result = '{0} * {1} = {2}'.format(intA,intB,intA*intB)
print(result) # 5 * 3 = 15

d = digital

intD = 5 
print('number{:^5d}'.format(intD)) # number  5  

intD = 12300
print('number {:,}'.format(intD)) # number 12,300

chapter-8

基本程式設計(三)

座標距離設計

x1 = eval(input('enter A point x coordinate'))
y1 = eval(input('enter A point y coordinate'))
x2 = eval(input('enter B point x coordinate'))
y2 = eval(input('enter B point y coordinate'))


distance = ((x1-x2)**2+(y1-y2)**2)**0.5
print('A coordinate is ( {}, {} )'.format(x1,x2))
print('B coordinate is ( {}, {} )'.format(y1,y2))
print('distance is {:.4f}'.format(distance))

chapter-9

選擇敘述 if

score = eval(input('your score ？'))
if score > 80: 
  print('over 80')
elif score > 60:
  print('ok, fine !!')
else:
  print('less 80')

chapter-10

for loop

for i in range(13,8,-1):
  print(i)
# 13
# 12
# 11
# 10
# 9

for i in range(1,7):
  print("@"*i)
# @
# @@
# @@@
# @@@@
# @@@@@
# @@@@@@

可以練習寫出一個 9 * 9 乘法表

# bla... bla...

Chapter-11

for loop (二)

for i in range(8):
  for j in range(8):
    print(i,j,sep='',end=' ')
    '''
    sep -> separate
    end -> default end='\n'
    '''
  print() # print 會有換行的結果

Chapter-12

while loop & random

n = int(input('enter number:'))
i=1
while i<=n:
  print('@'*i)
  i += 1

import random
number = int(input('enter password number (0~9):'))

pwd = random.randint(0,9)
print(pwd)

while pwd != number:
  number = int(input('input pwd again (0~9):'))
  print(pwd,number)
print('successfully !!!')
