如何获取用户输入耗时并赋值给变量（打字游戏场景）

要实现统计用户输入每个单词的耗时（毫秒级），可以借助Python的time模块记录时间差，以下是修改后的完整代码：

from random import choice, randint
import time  # 导入时间模块

wrds = ['skateboard','mouse','river','simple','learn','sky','why','loser','lose','front','back','end','when','underline','flip','phone','puppet','doll','seven','wimpy','ski','charisma','wither','mine','craft','perish','list','python','name','age','climb','my','mine','plough','pull','zebra','cub','lion','zero','five','read','write','minus','plus','addition','China','Japan','united','states','of','and','will','America','north','south','west','east','bunny','rabbit','hare','plural','Persia','silent','loud','very','garlic','onion','tiger','specific','love','world','earth','murder','mud','identification','sign','maths','math','mathematics','science','scientific','history','geography','school','number','ten','french','speak','language','japanese','chinese','korean','Korea','bracket','square','circle','curly','triangle','hexagon','pentagon','shape','submissive','submit','male','female','gender','live','die','death','string','integer','plug','fraction','fact','opinion','mountain','type','typing','game','super','brother','sister','mother','mom','mama','father','dad','dada','papa','baby','family','you','try','except','that','myself','I','crime','criminal','jail','prison','fight','tell','talk','turn','curl','outlet','media','lap','top','dog','cat','cut','strategy','float','point','programmer','ritual','sinister','lover','kill','killer','knife','gun','half','shoot','president','presidency','promise','cling','cross','great','good','thumb','pinky','pink','blue','red','white','black','purple','pink','system','operate','language','spanish','flinch','ball','sphere','cube','cuboid','dinosaur','win','winner','silly','store','buy','home','make','house','clock','time','one','eleven','twelve','thirteen','teenager','young','old','book','electricity','motor','oil','wing','hub','colonel','star','sky','solar','eclipse','gum','eat','exam','assessment','study','pencil','eraser','sharpener','telephone','cell','honey','comb','bee','honeycomb','queen','prince','king','worker','trip','shrimp','innovate','creative','creat','screen','the','at','pie','trigonometry','geometry','algebra','basic','product','company','own','ownership','ship','relationship','oat','oatmeal','meal','bowl','plate','tab','goo','goop','bad','dab','lip','mouth','punch','bag','carry','care','an','stiff','still','it','thing','grip','happy','sad','drought','wet','cow','bull','sheep','embitterment','imprompt','impromptu','dilapidated','nest','bird','dream','egg','snake']
score = 0
multp = 1
word = choice(wrds)

while True:
    # 记录输入开始时间
    start_time = time.perf_counter()
    user_input = input(f'{word}: ')
    # 记录输入结束时间
    end_time = time.perf_counter()
    
    # 计算耗时，转成毫秒并保留两位小数
    input_time_ms = round((end_time - start_time) * 1000, 2)
    
    if user_input == word:
        score += multp
        multp = randint(1,3)
        word = choice(wrds)
        # 正确输入后显示耗时
        print(f'输入耗时：{input_time_ms} 毫秒')
    else:
        print('\nAgain!\n')
    
    print(f'\nScore!: {score}\n')

关键修改说明 #

• 导入time模块：用perf_counter()获取高精度时间，更适合短间隔时间测量
• 时间点记录：在提示输入前记起始时间，输入完成后记结束时间
• 耗时计算：通过时间差转换为毫秒，用round()控制小数位数，结果存入input_time_ms变量，可用于分数计算、数据存储等场景

如果要优化分数逻辑（比如耗时越短加分越多），可以调整分数计算部分，示例：

# 耗时低于500毫秒额外加1分
score += multp + (1 if input_time_ms < 500 else 0)
