Python typewriter function returning none when used within input?-CodePudding

    import random,sys,time,os 
os.system("cls")
def dialogue(passage):              # Function for dialogue to type slowly
     for letter in passage:
         sys.stdout.write(letter)
         sys.stdout.flush()
         time.sleep(0.1) 
name = input(dialogue("Hi, WHat is your name?"))

the input would pop up in the terminal as "Hi, WHat is your name?"NONE. is there any way I can change this to just return the input without it stating NONE where the output should be?

CodePudding user response：

Just add return '' to the end of the dialogue function:

def dialogue(passage):
    for letter in passage:
         sys.stdout.write(letter)
         sys.stdout.flush()
         time.sleep(0.1) 
    return ''
         
name = input(dialogue("Hi, What is your name? "))
