对比python和javascript

 

python:

 

print("hi!")

variable = 0
variable = "abcd"
print(variable)

num1 = 10
num2 = 10.0

num1 = float(num1)
num2 = int(num2)
print(num1,num2)

print(num1)
print(num2)

text1 = "I'm aprogrammer"
text2 = "I'm aprogrammer"

print(500+350)
print(500*300)
print(78983-24897)
print(573289/4378)

print(0.3-0.2)
print(0.3/0.2)

print(pow(4,2))
print(pow(4,2,3,))

import math
num = -4
num = abs(num)
print(math.sqrt(num))

a = 62
b = 21
c = a&b
print(c)

date = "2022.11.20"
day = "world cup day"
text = date + " " + day
print(text)

name = "Adam Smith"
print(name.lower())
print(name.upper())

text = "Python/n"
print(text*9)

 

javascript:

 

let obj1 = {
    name:'吉吉喵',
    money: 99,
}

let obj2 = {
    name:'雷电猴',
    money: 10,
}

function addMoney(obj, n) {//给对象加钱
    obj.money += n
    console.log(`${obj.name}获得了${n}块钱`)
}

function giveMoney(sender,receiver, n) {//把钱从一个对象转到另一个对象
    receiver.money += n
    sender.money -= n
    console.log(`${sender.name}给了${receiver.name}${n}块钱`)
}

function display(obj) {
    console.log(`${obj.name}有${obj.money}块钱`)
}

display(obj1)
display(obj2)
addMoney(obj2, 10)
display(obj2)
giveMoney(obj1, obj2, 20)
display(obj1)
display(obj2)
