Please tell me how to deal with selenium's StaleElementReferenceExceptiont error

Question

The StaleElementReferenceException occurs when you execute the code below.
It didn't come out at first, but it's almost 100% now.

Tried

Sleep failed to set the wait time
I couldn't put the elements of x_path in the array and put them in the for statement
```
for window dd:
    ddd.append(w)
```

Failed to set wait time in sleep

Failed to put elements of x_path in array and for statement

for window dd:
    ddd.append(w)

I'm a beginner, so the way I do it may be strange...
I would appreciate it if you could tell me how to deal with it.

Below are some of the code and the error content.

Code

browser=webdriver.Chrome(executable_path=r"C:\Users\wakar\chromedriver.exe")

browser.get(url)

browser.find_element_by_xpath("/html/body/header/div/nav/ul/li[5]US>") .click()

browser.find_element_by_xpath("//*[@id='container']/main/div[2]/div/div/section/div[1]/form/input").send_keys(code)

browser.find_element_by_xpath("//*[@id='container']/main/div[2]/div/div/section/div[1]/form/button").click()

for i in range (click_times):
    browser.find_element_by_xpath("//*[@id='loading']/td/div/a").click()

ddd=browser.find_elements_by_xpath("//*[@id='container']/main/div[2]/div/div/section/div[2]/table/tbody/tr")

    
for date inddd:
    print(date)
    date_tmp_tmp = date.text
    date_tmp = date_tmp_tmp.split(',1)
    if re.compile('[0-9]{2}'+'/'[0-9]{2}').search(date_tmp[0]):
        date_h.append(date_tmp[0])

How about ignoring exceptions in try?

from selenium.common.exception.exception import StaleElementReferenceException

for date inddd:
    try:
        print(date)
        date_tmp_tmp = date.text
        date_tmp = date_tmp_tmp.split(',1)
        if re.compile('[0-9]{2}'+'/'[0-9]{2}').search(date_tmp[0]):
            date_h.append(date_tmp[0])
    exceptStaleElementReferenceException:
        continue

Why don't you change the following parts? The line marked "#" is the changed line.

dd=browser.find_elements_by_xpath("//*[@id='container']/main/div[2]/div/div/section/div[2]/table/tbody/tr")

ddd_text = [date.text for date inddd]#

for date inddd_text:#
    print(date)
    date_tmp_tmp=date#
    date_tmp = date_tmp_tmp.split(',1)
    if re.compile('[0-9]{2}'+'/'[0-9]{2}').search(date_tmp[0]):
        date_h.append(date_tmp[0])
