python代码编写使用英文输入法
控制台的读取和输入：
input输入进去的是字符串
eval
在jupyter用shift+tab跳出解释文档
运算符：
+：加
-：减
*：乘
/：除
//：整除
**：指数幂
%：取余
增强型赋值运算：
+=：自加
-=：自减
*=：自乘
/=：自除
代码：
celsius=float(input('Enter a degree in Celsius:'))
fahrenheit = (9 / 5) * celsius + 32
print("{0} Celsius is {1} Fahrenheit" .format(celsius,fahrenheit))
代码：
import math
radius,length=eval(input('Enter the radius and length of a cylinder:'))
area = radius **2 * math.pi
volume = area * length
print("The area is {0}".format("%.4f"% area))
print("The volume is {0}".format("%.1f"% volume))
代码：
feet=float(input('Enter a value for feet:'))
meters=feet * 0.305
print("{0} feet is {1} meters".format(feet,meters))
代码：
water=float(input('Enter the amount of water in kilograms:'))
initialtemperature=float(input('Enter the initial temperature:'))
finaltemperature=float(input('Enter the final temperature:'))
Q = water * (finaltemperature - initialtemperature) * 4184
print("The energy needed is ",Q)
代码：
balance,interestrate=eval(input('Enter balance and interest rate (e.g., 3 for 3%):'))
interest=balance * (interestrate / 1200)
print("The interest is {0}".format("%.5f"%interest))
代码：
v0,v1,t=eval(input('Enter v0,v1,and t:'))
a=(v1 - v0) / t
print("The average acceleration is {0}" .format("%.4f"% a))
代码：
number=float(input("Ener the monthly saving amount :"))
number1=0
for i in range(6):
number1=(number+number1) * (1 + 0.00417)
print("After the sixth month,the account value is {0}".format("%.2f"% number1))
代码：
number=float(input("Enter a number between 0 and 1000:"))
bai=int(number/100)
shi=int(number/10%10)
ge=int(number%10)
he=bai+shi+ge
print("The sum of the digits is ",he)
体会：
通过初时Python以及对他的语言元素的认识，对于python有了很深的印象
