random :third-party libraries
common usage:
random.randint(10)
random.randrange(10)
random.choice(1,2)
random.choices
random.shuffle([1,2,3])
so on
create verification code
def v_code():
code=""
for i in range(5)
add=randdom.choice[random.randrange(10),chr(random.randrange(65,91)]
code+=add
print(code)
v_code()
def v_code():
code=""
for i in range(5):
if i==randrange(0,2)
add=randrange(10)
else:
add=chr(random.randrange(65,91))
code+=add
print(code)
v_code()
