Write A Python Program To Find The Sum Of The Series:- X - X**2/2! + X**3/3! - X**4/4! + X**5/5! - X**6/6!

What I have tried:

Python

X = int(raw_input("Enter the value for x:"))
j = int(raw_input("Enter The value for j:"))
Sum = 0
Fact = 1
Sign = 1
for i in range(1,x+1):
     for i in range(1,j+1):
               Fact = Fact*1
Sum += (Sign*(X**i)/Fact*j

X = int(raw_input("Enter the value for x:"))
j = int(raw_input("Enter The value for j:"))
Sum = 0
Fact = 1
Sign = 1
for i in range(1,x+1):
for i in range(1,j+1):
Fact = Fact*1
Sum += (Sign*(X**i)/Fact*j
here a red line appears saying there is syntax error

Solution 1

You declare X (upper case) in line 1, but you later refer to x (lower case), which does not exist.
The line

Python

Fact = Fact*1

does not do anything useful.
I also suspect the last line of your code should be indented the same as the previous line.

Python

for i in range(1,x+1):
     for i in range(1,j+1):

Using i as the counter of 2 nested for loops is an error too.

Python

Sum += (Sign*(X**i)/Fact*j

Here you gave 2 ( bit only 1 )

Advice: take a sheet of paper and write all what you need with 1 line per element in the sum and 1 column for each piece of element.
Then your program will need to prepare each pieces and then update the sum.
Don't mind using comments in code.
