Hello this is Gulshan Negi Well, I am writing a program for finding sum of natural numbers but it shows some error at the time of execution. Source Code: n = int(input("Enter the number:" )) sum=0 if n > 1: for i in range(1,n+1): sum+=i: print("The sum o
11. Difference of Squares Sum and Sum of Squares Write a Python program to calculate the difference between the squared sum of the first n natural numbers and the sum of squared first n natural numbers.(default value of number=2). Sample Solution: Python Code: defsum_difference(n=2):sum_...
我们可以用以下代码扩展功能,比如添加可视化部分: importmatplotlib.pyplotaspltclassSumCubes:def__init__(self,n):self.n=ndefsum_of_cubes(self):return(self.n*(self.n+1)//2)**2defplot_cubes(self):data=[i**3foriinrange(1,self.n+1)]plt.plot(data)plt.title('Cubes of Natural Numbers')p...
妙用Python内置函数int()快速计算等比数列前n项和 本文要点在于Python内置函数int()的用法,所以计算等比数列前n项和时没有使用数学上的公式Sn=a1*(1-q^n)/(1-q)。 一般遇到这样的问题,很容易想到使用循环来实现,以计算1+2+4+8+16+...+2^199为例,也就是计算比值q=1且数列首项a1=1的等比数列前200项...
In this python program we will learn to calculate the average of number for N numbers. Average is the sum of items divided by the number of items. Here, we’ll calculate the sum and average of a natural number as listed by the user. Algorithm: Declare variables n (for the number of ...
This improves the efficiency of your code. Next, you should process the data to record the number of digits and the status of the message:Python 8for i, line in enumerate(data): 9 case, message = line.split("\t") 10 num_digits = sum(c.isdigit() for c in message) 11 digit_...
