[英]I'm trying to make a fequency analysis programme using python but i'm having issues
[英]I'm having issues using generators with the input function in python 3
def prime():
n = 1000
if n<2:
return 0
yield 2
x = 3
while x <= n:
for i in range(3,x,2):
if x%i==0:
x+=2
break
else:
yield x
x+=2
#if i try to call each yielded value with an input function i don't get anything!
def next_prime():
generator = prime()
y = input('Find next prime? yes/no or y/n: ')
if y[0].lower == 'y':
print(generator.next())
next_prime()
#but if i call the function without using an input i get my values back
generator = prime()
def next_prime():
print(next(generator))
next_prime()
如何使第一個next_prime
function 與輸入 function 一起工作。 如果我嘗試用輸入 function 調用每個產生的值,我什么也得不到,但是如果我在不使用輸入的情況下調用 function,我會得到我的值。 是不是發電機不能與輸入 function 一起工作?
你犯的錯誤是你忘記了lower關鍵字的圓括號
def next_prime():
generator = prime()
y = input('Find next prime? yes/no or y/n: ')
#forgot the round brackets
if y[0].lower() == 'y':
print(next(generator))
next_prime()
