Find factorial using Python function – using for loop
#Pyton program to find factorial of a number
def factorial(num):#function definition
fact=1
for i in range(1, num+1):#for loop for finding factorial
fact=fact*i
return fact #return factorial
number=int(input("Please enter any number to find factorial: "))
result=factorial(number)#function call and assign the value to variable result
print("The factorial of %d = %d"%(number,result))
When the above code is executed, it produces the following results
Please enter any number to find factorial: 6
The factorial of 6 = 720
Find factorial using Python function – using while loop
def factorial(num):#function definition
fact=1;
i=1
while i<=num:
fact=fact*i
i=i+1
return fact
num=input("Enter a number..");
result=factorial(num)
print("factorial of the number: %d" %result)
factorial(num)#function call
When the above code is executed, it produces the following results
Enter a number..5
factorial of the number: 120
Programming approaches for implementing these program
- Take a number as input from the user and stored in variable number for finding factorial
- Declare a python function to find factorial
- Inside the function, declare the variable fact and initialise as 1
- Inside the function, find the factorial of a given number using for loop in Python
- Run the loop from given number until 1 and multiply numbers
- Call the factorial() function and assign the output to variable result
- the factorial of the given number is displayed using the print() function in Python

operator is used to get hidden names due to variable scopes so that you can still use them. The scope resolution operator can be used as both unary and binary. You can use the unary scope operator if a namespace scope or global scope name is hidden by a particular declaration of an equivalent name during a block or class. For example, if you have a global variable of name my_var and a local variable of name my_var, to access global my_var, you'll need to use the scope resolution operator.

Python file method flush() flushes the internal buffer, like stdio's fflush. This may be a no-op on some file-like objects.
Python automatically flushes the files when closing them. But you may want to flush the data before closing any file.

Accessing a binary file from a C++ program (by not using the old C functions) requires firstly attaching a stream variable to the file. The usual stream classes ofstream (output file stream) and ifstream (input file stream) are still the types of streams to use. A an additional type called an fstream is provided which allows for files that can be written to and read from if this is a desirable property (in the design of database type programs, this is often the case).
Before any operation can take place on a file, it of course must be <i>opened</i>, and when you are finished with the file, it should be closed to avoid loss of data.

Source Code: Using if...elif...else
num = float(input("Enter a number: "))
if num > 0:
print("Positive number")
elif num == 0:
print("Zero")
else:
print("Negative number")
Source Code: Using Nested if
num = float(input("Enter a number: "))
if num >= 0:
if num == 0:
print("Zero")
else:
print("Positive number")
else:
print("Negative number")

The range() function returns a sequence of numbers, starting from 0 by default, and increments by 1 (by default), and stops before a specified number. Basically in python range(n) iterates n times, which is of exclusive nature that is why it does not give last value when it is being printed, we can create a function which gives inclusive value it means it will also print last value mentioned in range.
