How can call the function when achieve the condition?-CodePudding

How can I call the function when achieve the condition. I made some function, but the function just call once time. It is not be able to use next time, unless I run the coding again.

If I just have one function, it is able to call, when achieve a certain condition.


def once():
    ret = False 
    while True:
      if driver.find_element(By.ID, "ONCE"):
         driver.refresh()
         ret = True
    return ret

once()

def twice():
    ret = False
    element = driver.find_element(By.ID, "Twice")
    while True:
       if driver.find_element(By.ID, "Twice"):
          elmenet.click()
          ret = True
    return ret

twice()

I expect that the function can call automaically when achieve the condition.

But I don't how to do.

For example,

when I achieve the condition, the def will call automaically.

CodePudding user response：

you can use while loop while loop will keep running until the condition is true and will stop when it is false

x=10
def PRINT(): 
    print(str(x)   ' is greater than 0')
while x > 0 :
    PRINT()
    x=x-1
