我一直在研究计算房间均方值的代码。我的循环结构似乎出了点问题,有人可以帮助找到我的错误吗?谢谢!
def rms():
print("This program will calculate the RMS of your values.")
print()
n = int(input("Please enter the number of values you want
calculated: "))
total = 0.0
for i in range(n):
x = float(input("Enter a desired values:"))
total = total + math.sqrt(x)
print("\nThe Root Mean Square is:", math.sqrt(total/n))
答案 0 :(得分:0)
没关系,我从阅读中看到您想要thisMethod
中的所有内容,但我相信您希望rms()
中的所有内容都应谨慎处理缩进,以使函数的某些部分不会超出功能范围,尽管可以,但不能确定所需的输出。
rms()
import math def rms(): print("This program will calculate the RMS of your values.") print() n = int(input("Please enter the number of values you want calculated: ")) total = 0.0 for i in range(n): x = float(input("Enter a desired values:")) total = total + math.sqrt(x) print("\nThe Root Mean Square is:", math.sqrt(total/n)) rms()
答案 1 :(得分:0)
您犯了一个错误total = total + math.sqrt(x)
,错误是您应该找到平方x 而不是 x平方根,因此请尝试我的固定代码:-
def rms():
print("This program will calculate the RMS of your values.\n")
n = int(input("Please enter the number of values you want calculated: "))
total = 0.0
for i in range(n):
x = float(input("Enter a desired values:"))
total += x ** 2 #it means x powered by two
print("\nThe Root Mean Square is:", math.sqrt(total/n))
答案 2 :(得分:-1)
如果我正确地推断出,那么您想获取每个输入,对其求平方,求和并求和并求平方根。请记住,求平均时(寻找均值),只能除以最后的总和:
def rms():
total = 0.0
count = 0
while True:
x = input('enter value (enter nothing to stop):')
if x.strip() == '':
break
count += 1
total += float(x) ** 2
print('mean square root is:', math.sqrt(total/count))
# return math.sqrt(total / count)
