我如何将函数转换成整数?
原标题：How do I convert a function to an integer?
I can t find a way to get my dice simulator to convert a function to a string to an integer. I ve been trying to incorporate a how many sides plus how many rolls feature, and I can t figure it out.
import random
random.seed(12039810239874610293)
a = 1
b = input( How many sides would you like your die to have? )
r = input( How many times would you like to roll it? )
r = int(r)
r2 = r + 1
b = int(b)
def n():
for counter in range(1, r2):
random.randint(1, b)
return n2
n2_int = int(n2)
print( You rolled a , n2_int)
Although to be fair, I am a relative noob to python, having put it down for about 2 years.
I ve used ChatGPT to solve it, but it hasn t helped, and have spent a while on stack overflow trying to fix it. Still displays variants of TypeError: Int() argument must be a string and ValueError: Invalid literal for int() with base 10: None
EDIT: Put in full code for clarity

this is a demonstration of how to do the said scenario
first is to get the how many sides and times and convert them into int before storing in a variable
import random
sides = int(input( How many sides would you like your die to have? ))
times = int(input( How many times would you like to roll it? ))
# the declaration above is stated in a simpler way as
# sides = input( string here )
# sides_int = int(sides)
now let s create a function with parameters in which the function will use to properly do the instructions you want
def roll_dice(sides, times):
for roller in range(0, times):#this will determine how many rolls
rolled = random.randint(1, sides) #this roll the dice based on sides
print(rolled) #prints the rolled number
now lets call the function
roll_dice(sides, times)
now to answer the question to pass the value to a variable, then you must have a storage for it since you want to successfully pass the value to a variable, you must do it properly, as per your request to transfer it as int to a variable, here s how you can do it, you can notice that we placed the number of times outside, since we specified that rolling the dice is a function and how many times it must be rolled is equivalent on how many times should we call the function
def pass_the_dice(sides): #this is your function that only requires sides
return random.randint(1, sides)
for counter in range(0, times):
rolled_value = pass_the_dice(sides)
print(f"You rolled :{rolled_value}")
I hope I made it clearer for you
your code snippet is missing data. Where does r2 come from? you are not passing it to your function as an argument:
if you want the function to use a value then you have to pass a value to it. ex:
def sum_two_numbers(a, b):
result = a + b
print(result)
then you have to CALL the function.. meaning.. tell python use this function and change a , b with real values..
sum_two_numbers(2,5)
this will indeed return 7
It looks like what you are trying to achieve is something like this
import random
rolls = int(input("How many rolls?")) #create an int variable for rolls
sides = int(input("How many sides?")) #create an int variable for die sides
def n(r2, b): #define positional arguments to your function
for x in range(1, r2): #use your args in function
print(random.randint(1, b)) #print the random result of your die
n(rolls, sides) #your function call passing your previously created values
print(f You rolled a {sides} sides die {rolls} times ) #fancy report
