如果要仅在文件修改时每60秒更新一次DataFrame：

import time
import os
import pandas as pd

SECONDS_BETWEEN_UPDATES = 60

print('csv_file updater started, press ctrl+c to exit')

try:
    last_modified_time = 0
    while True:
        new_modified_time = os.path.getmtime('data.csv')
        if new_modified_time > last_modified_time:
            csv_file = pd.read_csv('data.csv', encoding='utf-8')
            last_modified_time = new_modified_time
            print('Dataframe Updated')
        
        time.sleep(SECONDS_BETWEEN_UPDATES)

except KeyboardInterrupt:
    print('File update stopped by user')

字符串
或者，如果您只想每隔60秒重新读取一个csv，即使它没有被修改，它会变得更简单：

import time
import pandas as pd

SECONDS_BETWEEN_UPDATES = 60

print('csv_file updater started, press ctrl+c to exit')

try:
    while:
        csv_file = pd.read_csv('data.csv', encoding='utf-8')
        print('Dataframe Updated')
        time.sleep(SECONDS_BETWEEN_UPDATES)

except KeyboardInterrupt:
    print('File update stopped by user')

除了最后一条之外，您可以随意删除print语句，如果您不希望使用pass替换它。
使用Control+C停止其运行
