Question

我需要将rand_Num添加到名为Rand_Number的空白txt文件中。我需要做100000次。这是我的代码... ＃导入所需的库

import random
import turtle

# screen variables

wn_wid = 550
wn_length = 350
wn_title = "Random output"
wn_background_col = "#3d3d3d"
wn_tracer = 0

# creates and configures window

wn = turtle.Screen()
wn.setup(wn_wid, wn_length)
wn.title(wn_title)
wn.bgcolor(wn_background_col)
wn.tracer(wn_tracer)

# creates text

text = turtle.Turtle()
text.speed(0)
text.color("#ffffff")
text.pu()
text.hideturtle()

# text variables

font = "Comic Sans MS"
font_size = 48
alignment = "center"

# rep_num variable

rep_Num = 0

# central loop

# loop repeat variable

repeats = 100000

 # main loop

 for reps in range(repeats):

     # adds 1 to rep_Num variable

    rep_Num += 1

    # generates random number

    rand_Num = random.randint(0, 100)

    # puts text on screen

    text.clear()
    text.write(str(rep_Num) + ": " + str(rand_Num), align=alignment, font=(font, font_size, "normal"))

    # checks to see whether it needs to close win

    if rep_Num == repeats:
        wn.bye()
        break

    # updates window

    wn.update()

这就是我的全部代码，并且都可以按我的要求工作。我只需要在循环中做一些事情，就可以让我将rand_Num变量添加到名为Rand_Numbers的txt中的新行中

Answer 1

我使用CSV模块完成此操作，这将使您可以随着项目的增长轻松添加其他数据。即使这不是您的意图，生成的文件仍可以轻松用于数据分析目的。如果确实需要，也可以通过这种方式生成文本文件。

我添加了此功能：

def write_random(rand_Num):
    num = [rand_Num]
    with open("random_values.csv", "a", newline='', encoding="utf-8") as csvfile:
        writer = csv.writer(csvfile)
        writer.writerow(num)

它会生成一个csv文件（如果您想对数据或其他内容进行数据分析，则可以通过Excel处理），并将每个随机值放在单独的一行上。

如果您确实想要一个文本文件，则只需将扩展名从.csv更改为.txt，只要每行仅包含一个数据即可。

这是完整的工作代码：

import random
import turtle
import csv
def write_random(rand_Num):
    num = [rand_Num]
    with open("Rand_Number.csv", "a", newline='', encoding="utf-8") as csvfile:
        writer = csv.writer(csvfile)
        writer.writerow(num)
# screen variables
wn_wid = 550
wn_length = 350
wn_title = "Random output"
wn_background_col = "#3d3d3d"
wn_tracer = 0

# creates and configures window
wn = turtle.Screen()
wn.setup(wn_wid, wn_length)
wn.title(wn_title)
wn.bgcolor(wn_background_col)
wn.tracer(wn_tracer)

# creates text

text = turtle.Turtle()
text.speed(0)
text.color("#ffffff")
text.pu()
text.hideturtle()

# text variables

font = "Comic Sans MS"
font_size = 48
alignment = "center"

# rep_num variable

rep_Num = 0

# central loop

# loop repeat variable

repeats = 100000

# main loop

for reps in range(repeats):

    # adds 1 to rep_Num variable

    rep_Num += 1

    # generates random number

    rand_Num = random.randint(0, 100)
    write_random(rand_Num)
    # puts text on screen

    text.clear()
    text.write(str(rep_Num) + ": " + str(rand_Num), align=alignment, font=(font, font_size, "normal"))

    # checks to see whether it needs to close win

    if rep_Num == repeats:
        wn.bye()
        break

    # updates window

    wn.update()

您可以使用with open(file) Synthax。我会写这样的东西：

with open('Rand_Numbers', 'w') as f:
    for reps in range(repeats):

        # adds 1 to rep_Num variable

        rep_Num += 1

        # generates random number

        rand_Num = random.randint(0, 100)
        f.write(str(rand_Num))

        # puts text on screen

        text.clear()
        text.write(str(rep_Num) + ": " + str(rand_Num), align=alignment, font=(font, font_size, "normal"))

        # checks to see whether it needs to close win

        if rep_Num == repeats:
            wn.bye()
            break

        # updates window

        wn.update()

顺便说一句，您应该删除rep_Num = 0和

if rep_Num == repeats:
       wn.bye()
       break

在您的代码中

，因为循环已经完成了工作。 wn.bye()将在循环后添加。
