Python Installation

  1. Download python
  2. Check "Add Python 3.7 to PATH"
  3. Click "Install Now"
  4. Download "get-pip.py"
  5. While finish installation of python 3.7, open the command line
  6. change the directory to where the file is, then key in the command "python get-pip.py"

Introduction to

  1. High-level programming language
  2. Design Philosophy:
    • code readability
    • significant whitespace
    • simple and clear
  3. large and comprehensive standard library
  4. open source

Basic Construction

First of all,

      how to input and output testcases?

Please try the code below：

print("Hello, World!")

name = input("Please input your name: ")
print("Hello, " + name)
name = input("Please input your name: ")
id = input("Please input your student ID: ")
print("Welcome, ID " + id + ", Mr./Ms. " + name)

Operator

  • +   => add
  • -    => subtract
  • *   => multiplication
  • /    => divide (float)
  • //   => divide (integer)
  • **  => power
  • %   => remainder

Variable Name

  1.  Must start with a letter or an underscore
  2.  The remainder of variable name may consist a number, a letter, or an underscore
  3.  Case sensitive
  4.  Avoid the remainder word
import keyword
keyword.kwlist

* Python3 import unicode

Type Conversion

  • Integer  =>  int()
  • float       =>  float()
  • string     =>  str()
  • boolean =>  boolean()

Condition

if [condition]:
    [statement]
elif [condition]:
    [statement]
else:
    [statement]

Loop - for

Loop - while

for [variable] in [array]:
    [statement]

#------------------------
for [variable] in range([3 parameters]):
    [statement]

# parameters of range:
# 1. starting value
# 2. ending value
# 3. increment
while [condition]:
    [statement]

| Default Input

LAB - 02

| String Input

print(input() * 2)
this_is_the_string = "I am"

print(this_is_the_string + " nobody.")
print(this_is_the_string * 3)

LAB - 03

| Datatype Concersion

type_string = input("Please enter your favorite number: ")
print(type_string * 2)

type_integer = int(input("Please enter your favorite number again: "))
print(type_integer * 2)

type_float = float(input("Please enter your favorite number again and again: "))
print(type_float * 2)

LAB - 04

| Game Design ~ 勇者の始まる

1. 自我介紹：姓名、年齡、性別

2. 能力：血量、攻擊力、防禦力、幸運值、擊中值

hero_name = input("君の名は？ ")
hero_age = input("あなたの年齢は？ ")
hero_gender = input("あなたは男ですか？女ですか？ ")

print("ようこそこの世界え、勇者 " + hero_name + "。")
print("これからはあなたの最初の状態：")
print("名前： " + hero_name)
print("年齢： " + hero_age)
print("性別： " + hero_gender)

hero_HP = int(input("HP： "))
hero_attackValue = int(input("攻撃力： "))
hero_defenseValue = int(input("防御力： "))
hero_luckValue = int(input("ラック： "))
hero_hitValue = float(input("ストライク値： "))
print("\n")

| Game Design ~ バケモノのデータ

1. 魔物資料：血量、閃躲值、攻擊力、防禦力 

print("これからはモンスターの情報")

monster_HP = int(input("HP： "))
monster_attackValue = int(input("攻撃力： "))
monster_defenseValue = int(input("防御力： "))
monster_dodgeValue = float(input("ダッジ値： "))

print("\n")

LAB - 06

| Game Design ~ 戦いの瞬間(1)

1. 計算勇者成功攻擊怪獸的機率

hint:

1. 機率 = (勇者擊中值 - 魔物閃避值) / 1000 * 100(%)

hero_hitRate = (hero_hitValue - monster_dodgeValue) / 1000 * 100

LAB - 06

| Game Design ~ 戦いの瞬間(2)

2. 使用亂數作為怪獸成功閃躲的機率，並輸出是否攻擊成功

hint:

1. 引入random函式庫

2. random.randint(1, 100)

import random


hero_hitRate = (hero_hitValue - monster_dodgeValue) /1000 * 100
monster_dodgeRate = random.randint(1, 100)

if hero_hitRate > monster_dodgeRate:
    print("HIT!")
else:
    print("MISS~")

LAB - 06

| Game Design ~ 戦いの瞬間(3)

3.使用亂數取怪獸的幸運值，倘若小於勇者的幸運值則輸出暴擊(5倍攻擊)

hint:

1. random.randint(1, 1000)

import random

hero_criticalAttackerValue = hero_attackValue * 5
hero_hitRate = (hero_hitValue - monster_dodgeValue) /1000 * 100
monster_dodgeRate = random.randint(1, 100)
monster_luckValue = random.randint(1, 1000)


if hero_hitRate > monster_dodgeRate and hero_luckValue > monster_luckValue:
    print("CRITICAL~~!")
elif hero_hitRate > monster_dodgeRate:
    print("HIT!")
else:
    print("MISS~")

LAB - 07

| Game Design ~ 世界のために、勇者を、戦おう！

1. 利用迴圈及判斷式，如果擊中怪獸則減少怪獸HP，若沒有擊中則減少勇者的HP，直到其中一方HP歸零倒地

hint:

1. while(魔物或勇者血量未歸零) => 進入迴圈

2. 若擊中，魔物血量 - (勇者攻擊力 - 魔物防禦力)；

     若未擊中，勇者血量 - (魔物攻擊力 - 勇者防禦力)

while hero_HP > 0 or monster_HP > 0:
    if(Critical Hit):
        monster_HP -= (hero_criticalAttackValue - monster_defenseValue)
    elif(Hit):
        monster_HP -= (hero_attackValue - monster_defenseValue)
    else:
        hero_HP -= (monster_attackValue - hero_defenseValue)
