[英]How do I use input in def (Python)
I'm a newbie when it comes to coding.在编码方面,我是新手。 I would highly appreciate it if you can help me solving my problem regards to coding.
如果您能帮助我解决有关编码的问题,我将不胜感激。 I tried to use input in my def but doesn't work.
我尝试在我的 def 中使用输入但不起作用。
import random
def estimate_pi(n):
num_point_circle = 0
num_point_total = 0
for _ in range(n):
x = random.uniform(0,1)
y = random.uniform(0,1)
distance = x**2 + y**2
if distance <= 1:
num_point_circle += 1
num_point_total += 1
return 4 * num_point_circle/num_point_total
n = input("Enter A Random Number")
result = estimate_pi(n)
print (result)
Input function of python is a string whereas your code is expecting an integer.输入 python 的 function 是一个字符串,而您的代码需要一个 integer。 Simply cast n as integer and it should be fine.
只需将 n 转换为 integer 就可以了。
n = int(input("Enter A Random Number"))
You have to convert the input from string
to int
: estimate_pi(int(n))
The correct code would be:您必须将输入从
string
转换为int
: estimate_pi(int(n))
正确的代码是:
import random
def estimate_pi(n):
num_point_circle = 0
num_point_total = 0
for _ in range(n):
x = random.uniform(0,1)
y = random.uniform(0,1)
distance = x**2 + y**2
if distance <= 1:
num_point_circle += 1
num_point_total += 1
return 4 * num_point_circle/num_point_total
n = input("Enter A Random Number")
result = estimate_pi(int(n))
print (result)
You've to convert your input type to integer:您必须将输入类型转换为 integer:
import random
def estimate_pi(n):
num_point_circle = 0
num_point_total = 0
for _ in range(n):
x = random.uniform(0,1)
y = random.uniform(0,1)
distance = x**2 + y**2
if distance <= 1:
num_point_circle += 1
num_point_total += 1
return 4 * num_point_circle/num_point_total
n = input("Enter A Random Number")
n = int(n) #converting n from string to integer
result = estimate_pi(n)
print (result)
I guess, you are asking about using the "input()" method inside the "def" block.我想,您是在询问在“def”块中使用“input()”方法的问题。
I tried as below and it worked.我尝试如下,它奏效了。
Let me know what exactly is the error that you are getting让我知道你得到的错误到底是什么
def estimate_pi():
n =int input("Enter A Random Number")
num_point_circle = 0
num_point_total = 0
for _ in range(n):
x = random.uniform(0,1)
y = random.uniform(0,1)
distance = x**2 + y**2
if distance <= 1:
num_point_circle += 1
num_point_total += 1
return 4 * num_point_circle/num_point_total
result = estimate_pi()
print (result)
