python - 如何定义用户输入？

Question

from random import randint  # This imports the required modules for the program to work
character = input(str("martian,plutonian,human or dog\n>>"))  # This asks the player what character they would like to play
strength = (randint(3, 20))  # This sets the range for the strength variable
speed = (randint(3, 20))  # This sets the range for the speed variable
height = randint(120, 183)  # This sets the range for the height variable (the variables are 100x the amount that the task states)
#  The reason as to why the height value is 100x what it is meant to be is because the height is a decimal and the randint function only works with real numbers
height1 = height/100  # Because the values are 100x the required amount I divide them by 100
heart_rate = (randint(60, 110))  # This sets the range for the heart rate variable


if character: "martian"  # This makes the following only occur if the player inputs "martian"
strength += 3  #This adds 3 to the value of strength
speed +=2 #This adds 2 to the value of speed
if character: "plutonian"  #This makes the following only occur if the player inputs "plutonian"
heart_rate+=7 #This adds 7 to the value of heart rate
height1+=1 #This adds 1 to the value of height
if character: "human" #This makes the following only occur if the player inputs "human"
heart_rate+=3 #This adds 3 to the heart rate value
if character: "dog"
height-=3 #This adds 3


print("Your strength is", strength)  # This prints the strength of the character
print("Your speed is", speed)  # This prints the speed of the character
print("Your heart rate is", heart_rate)  # This prints the heart rate of the character
print("Your height is", height1)  # This prints the height of the character


file_txt=open('Character Statistics.txt', 'a',) #This creates and names the text file
file_txt.write(str("Character Statistics:\n")) #This makes a title within the text document
file_txt.write("Your strength is:") #This prints text into the text file
file_txt.write(str(strength)+"\n") #This adds the strength value to the txt file
file_txt.write("Your speed is:") #This prints text into the text file
file_txt.write(str(speed)+"\n") #This adds the speed value to the txt file
file_txt.write("Your heart rate is:")  #This prints text into the text file
file_txt.write(str(heart_rate)+"\n") #This adds the heart rate value to the txt file
file_txt.write("Your height is is:") #This prints text into the text file
file_txt.write(str(height1)+"\n") #This adds the height value to the txt file

一旦玩家输入字符(例如火星人)，就会发生此错误: 文件“C:/Users/megam/Desktop/Martians/Martians.py”，第 2 行，位于 character = input(str("martian,plutonian, human or dogs\n>>")) # 这会询问玩家他们想扮演什么角色 文件“”，第 1 行，位于NameError:名称“martian”未定义

首先你应该确定意图。其次，对于火星人、狗、冥王星人和人类，if character==“martian”:必须将其从:更改为==。 p>

if character=="martian":  # This makes the following only occur if the player inputs "martian"
    strength += 3  #This adds 3 to the value of strength
    speed +=2 #This adds 2 to the value of speed
if character=="plutonian":  #This makes the following only occur if the player inputs "plutonian"
    heart_rate+=7 #This adds 7 to the value of heart rate
    height1+=1 #This adds 1 to the value of height
if character=="human": #This makes the following only occur if the player inputs "human"
    heart_rate+=3 #This adds 3 to the heart rate value
if character=="dog":
    height-=3 #This adds 3

你也应该改变character = input(str("火星人、冥王星人、人类或狗\n>>")) 至

character = raw_input(str("martian,plutonian,human or dog\n>>"))
