How can I generate a text using generator in python?

Question

I want to make a text using python generator

I'm a beginner and have started learning python recently , I have searched the web but didn't find anything useful

def make_text(n):
    b = ["hello"]
    yield n+b
n = ['how are you', 'what is your name']
for x in range(2):
    title = driver.find_element_by_xpath('//*[@id="title"]')
    title.send_keys(make_text(n))

I want to get :

hello how are you 
hello what's your name?

but i get this error :

object of type 'generator' has no len()

thanks in advance

A generator is meant to be used along with iteration over the generator. I don't se that in the code. Your code will not throw that error if you iterate over make_text() — rdas

title.send_keys checks the len of the argument passed ? If that is the case, then you can't pass the generator to the title.send_keys :). Anyway, why are you using generators for this ? — han solo

@hansolo I want to have "hello how are you " first time that the loop runs and hello what's your name second time — nima

@reportgunner I want it to be a generator exactly, I don't think it would be a generator without yield — nima

Here's a basic sample of what you can do. You need to iterate the yielded object,

def make_text(word):
    greetings = ['how are you', 'what is your name']
    for greet in greetings:
        yield "{} {}".format(word, greet)

def say():
    texts = ['hello',]
    for text in texts:
        x = make_text(text)
        for n in x:
            print(n)
            title = driver.find_element_by_xpath('//*[@id="title"]')
            title.send_keys(n)


say()

Output,

hello how are you
hello what is your name

A more beginner-friendly version of your code would be:

def make_text(n):
    b = ["hello"]
    return n + b

words = ['how are you', 'what is your name']

for word in words:
    text = make_text(word)
    print(text)
