Define def:

btw we usually starts with capital letter

def getName():
    return 'Jack'
def showNameCard():
    print('name:Jack')
    print('phone:0919570523')
    #that teacher's phone number 
showNameCard()
#print
#name:Jack
#phone:0919570523

find area of rectangle:

def getArea(length,width):
    return length*width
#use this method so then when sbd import your file it can run
if __name__=='__main__':
    x,y=map(int,input().split())
    print(getArea(x,y))

! multiplication

def fac(n):
    res = 1
    for i in range(n,1,-1):
        res*=i
    return res
#use this method so then when sbd import your file it can run
if __name__=='__main__':
    n=int(input())
    print(fac(n))

global variable:

it will find the variable outside of def

def fun(n):
    ans = 1
    for i in range(n,1,-1):
        ans*=i
    return ans
def fun2(n,m):
    return fun(n)/(fun(m)*fun(n-m))
if __name__ == '__main__':
    x,y=map(int,input().split())
    print(fun2(x,y))
#for C(m,n) multiplication

def fun(n):
    for i in range(2,n):
        if n % i ==

def fun(x):
    a=0
    for i in range(x,x//2):
        if x % i == 0:
            a+=1
    if a ==0:
        return True
    else:
        return False
if __name__=='__main__':
    n = int(input())
    for i  in range(z,n+1):
        if fun(i)==True:
            print(i)
