是否可以使用 Python 每 1 分钟向 excel 中注入一个数字？

Question

目前，我有一个代码每 5 秒更新一次 excel sheet。它将打印

0 400 800 800 800

1 400 800 800 800

2 400 800 800 800

我想弄清楚的是如何每隔 1 分钟将一个随机数添加到该列表中，例如，

0 400 800 800 800

1 **425** 800 800 800

2 400 800 800 800

此处显示的代码是我当前的代码，想知道是否有人可以帮助我，非常感谢:)。

import csv
import random
import time

x_value = 0
total_1 = 400 #voltage
total_2 = 800 #current(1)
total_3 = 800 #current(2)
total_4 = 800 #current(3)

fieldnames = ["Timestamp", "Voltage", "[L1] Current(1)", "[L1] Current(2)", "[L1] Current(3)"]

with open('test 4.0.csv', 'w') as csv_file:
    csv_writer = csv.DictWriter(csv_file, fieldnames = fieldnames)
    csv_writer.writeheader()
    
while True:
    with open('test 4.0.csv', 'a') as csv_file:
        csv_writer = csv.DictWriter(csv_file, fieldnames = fieldnames)
        
        info = {
            "Timestamp": x_value,
            "Voltage": total_1,
            "[L1] Current(1)": total_2,
            "[L1] Current(2)": total_3,
            "[L1] Current(3)": total_4
            }
        csv_writer.writerow(info)
        print(x_value, total_1, total_2, total_3, total_4)
        
        x_value += 1

    time.sleep(5) #controls the speed of the loop eg. 1 = 1sec

是的，您可以通过添加一个简单的标志来指示电压值是否应该随机化来做到这一点。

在你的循环之前，你可以通过

初始化一个标志

...
total_4 = 800 #current(3)
randomVoltageFlag = False # new flag
...

然后在你的循环中，检查标志是否为真并相应地分配值

While True:
    ...
    info = {
       ...
       "Voltage": random.randrange(200,500) if randomVoltageFlag else total_1,
       ...

最后，在循环结束时，您可以切换标志以翻转它以进行下一次迭代

randomVoltageFlag = not randomVoltageFlag

完整的mod化代码现在应该是

import csv
import random
import time

x_value = 0
total_1 = 400 #voltage
total_2 = 800 #current(1)
total_3 = 800 #current(2)
total_4 = 800 #current(3)
randomVoltageFlag = False # new flag

fieldnames = ["Timestamp", "Voltage", "[L1] Current(1)", "[L1] Current(2)", "[L1] Current(3)"]

with open('test 4.0.csv', 'w') as csv_file:
    csv_writer = csv.DictWriter(csv_file, fieldnames = fieldnames)
    csv_writer.writeheader()
    
while True:
    with open('test 4.0.csv', 'a') as csv_file:
        csv_writer = csv.DictWriter(csv_file, fieldnames = fieldnames)
        
        info = {
            "Timestamp": x_value,
            "Voltage": random.randrange(200,500) if randomVoltageFlag else total_1,
            "[L1] Current(1)": total_2,
            "[L1] Current(2)": total_3,
            "[L1] Current(3)": total_4
            }
        csv_writer.writerow(info)
        print(x_value, total_1, total_2, total_3, total_4)
        
        x_value += 1
        randomVoltageFlag = not randomVoltageFlag
    time.sleep(5) #controls the speed of the loop eg. 1 = 1sec

注意，这只是您的示例。 可以通过使用 % mod 运算符将标志替换为 x_value 来进一步优化， 但我会把那部分留给你去尝试。
