Sum from 1 to n, 2 to n, ... n in python

n=int(input())
sum=0
m=0
factorial=1

for i in range(1, n + 1):
    factorial *= i
    sum=factorial-m
    print(sum)

n = 5
s = sum(range(n+1))
for i in range(n):
    s -= i
    print(s)

import numpy as np
series = np.arange(1, n)
for i in range(series.size + 1):
    print(series[:i].sum())

Tính tổng S(n) = 1 + 2 + 3 + … + n bằng Python

Tính tổng S(n) = 1 + 2 + 3 + … + n.

tong = 0
n = 1

print("-- HỌC PYTHON TẠI FREETUTS.NET --- ")
print("Tính tổng S(n) = 1 + 2 + 3 + … + n")

# Nhập dữ liệu
print("hãy nhập vào số n: ")
n = int(input())

# Tính tổng
for i in range(0, n+1):
    tong += i

# In kết quả
print ("Tổng là: ", tong)

tong = 0
n = 1
i = 1

print("-- HỌC PYTHON TẠI FREETUTS.NET --- ")
print("Tính tổng S(n) = 1 + 2 + 3 + … + n")

# Nhập dữ liệu
print("hãy nhập vào số n: ")
n = int(input())

# Tính tổng
while i <= n :
    tong += i
    i += 1

# In kết quả
print ("Tổng là: ", tong)

Add a newline character in Python – 6 Easy Ways!

string = '''str1\nstr2....\nstrN'''

str='''Hello all!! \nI am Pythoner \nWelcome to the AskPython Tutorial''' 
print(str)

Hello all!! 
I am Pythoner 
Welcome to the AskPython Tutorial

'\n'.join(list)

lst = ['Python','Java','Kotlin','Cpp']
print("List before adding newline character to it:",lst)
lst = '\n'.join(lst)
print("List after adding newline character to it:\n",lst)

List before adding newline character to it: ['Python', 'Java', 'Kotlin', 'Cpp']
List after adding newline character to it:
 Python
Java

print("str1\nstr2")

print("str1\nstr2\n...\strN")

print("Hello Folks! Let us start learning.")
print("Statement after adding newline through print() function....")
print("Hello Folks!\nLet us start learning.")

Hello Folks! Let us start learning.
Statement after adding newline through print() function....
Hello Folks!

newline = '\n'
string = f"str1{newline}str2"

newline = '\n'
str = f"Python{newline}Java{newline}Cpp"

Python Program to Find Sum of Series [1+(1+2)+(1+2+3)+–+(1+2+3+–+n)]

Input: n=10
Output: 220

n = int(input("Enter value of n: "))

sum = sum([i*(i+1)/2 for i in range(1, n+1)])
print(sum)

Enter value of n: 10

n = int(input("Enter value of n: "))

sum = n*(n+1)*(2*n+4)/12
print(sum)

Enter value of n: 10

Python Program for Find sum of Series with n-th term as n^2 – (n-1)^2

Tn = n2 - (n-1)2

Sn = T1 + T2 + T3 + T4 + ...... + Tn

Input : 229137999
Output : 218194447

Input : 344936985
Output : 788019571

Given, Tn = n2 - (n-1)2
Or, Tn =  n2 - (1 + n2 - 2n)
Or, Tn =  n2 - 1 - n2 + 2n
Or, Tn =  2n - 1.
