I'm a student who's starting Python, and I'm asking you a question.

def std_weight(height, gender) :
    print(gender)
    print(type(gender))

    print(height)
    print(type(height))

    height = int(height)
    gender = int(gender)

    if gender == 1 :
        print(1)
        weight = height * height * 22
        print(weight)
        print("A man of height {0} has a standard weight of {1}.format(height, float(round(weight,2))))

    elif gender == 2 :
        print(2)
        print(type(height))
        weight = height * height * 21
        print(weight)
        print("A woman of height {0} has a standard weight of {1}.format(height, float(round(weight,2))))

print ("Standard Weight Saving Program\n")
height = input ("Enter the key: ")
gender = input ("Enter your gender (Male: 1, Female: 2) : ")
std_weight(height, gender)
