试着看看python中的数字是否为素数

Question

我正在尝试编写一个程序,告诉您数字是否为素数.这里是.正如您在运行该chkPrime函数时所看到的,一切都返回true.我为我的生活无法弄明白.有任何想法吗？

total=0

#Check if number is whole
def chkWhole(x):

    if(x%1 == 0):

        return True

    else:

        return False




#Check to see if the number divides evenly with all primes
def chkModtwo(n):
    a=n%2
    if chkWhole(a)==True:
        return True
    else:
        return False
def chkModthree(n):
    a=n%3
    if chkWhole(a)==True:
        return True
    else:
        return False
def chkModfive(n):
    a=n%5
    if chkWhole(a)==True:
        return True
    else:
        return False
def chkModseven(n):
    a=n%7
    if chkWhole(a)==True:
        return True
    else:
        return False


#Check if the number is a prime using other two functions

def chkPrime(n):
    if n== 1 or 2 or 3 or 5 or 7:
        return True

    if chkModtwo(n)==False and chkModthree(n)==False and chkModfive(n)==False and chkModseven(n)==False:
        return True
    else:
        return False

#while True:
#yourinput=raw_input("Enter to check if it is a prime")
#
#
#    youranswer=chkPrime(yourinput)
#
#    if youranswer==True:
#        print("Yes, it is a prime")
#    else:
#        print("No, this number is not prime")

Answer 1

if n== 1 or 2 or 3 or 5 or 7:

应该

if n == 1 or n == 2 or n == 3 or n == 5 or n == 7:

要么

if n in (1, 2, 3, 5, 7):
