def isValidPassword(password):
    lower = 'qwertyuiopasdfghjklzxcvbnm'
    upper = 'QWERTYUIOPASDFGHJKLZXCVBNM'
    digits = '0123456789'
    special = '~!@#$%^&*_+-=<>? '
    l = False
    u = False
    d = 0
    s = 0
    len = 0
    for char in password:
        if char in lower:
            l = True
        if char in upper:
            u = True
        if char in digits:
            d += 1
        if char in special:
            s += 1
        len += 1
    if len>=10 and l and u and d>=3 and s>=2:
        return True
    else:
        return False

print(isValidPassword('ASDFG123@ '))
print(isValidPassword('asdfg123@!'))
print(isValidPassword('ASDfg12j@!'))
print(isValidPassword('ASDf!123@'))
print(isValidPassword('ASDfg123@!'))
