1. Print all the no. between 1 to n

```n=int(input("Enter N: "))

for i in range(1,n+1):
print(i)
```

Output

```Enter N: 5
1
2
3
4
5
```

2. Print table of number

```n=int(input("Enter N: "))

for i in range(1,11):
print(n,"x",i,"=",i*n)
```

Output

```Enter N: 2
2 x 1 = 2
2 x 2 = 4
2 x 3 = 6
2 x 4 = 8
2 x 5 = 10
2 x 6 = 12
2 x 7 = 14
2 x 8 = 16
2 x 9 = 18
2 x 10 = 20
```

3. Print sum of n number

```n=int(input("Enter N: "))
s=0
for i in range(1,n+1):
s=s+i
print("Sum = ",s)
```

Output

```Enter N: 10
Sum = 55
```

4. Print factorial of n

```n=int(input("Enter N: "))
f=1
for i in range(n,0,-1):
f=f*i
print("Factorial = ",f)
```

Output

```Enter N: 4
Factorial =  24
```

5. Check prime number

```n=int(input("Enter N: "))
c=0
for i in range(1,n+1):
if n%i==0:
c=c+1
if c==2:
print(n,"is Prime")
else:
print(n,"is Not Prime")
```

Output

```Enter N: 131
131 is Prime
```

6. Check palindrome number

```n=int(input("Enter Number: "))
m=n
rev=0
while(n>0):
dig=n%10
rev=rev*10+dig
n=n//10
if rev==m:
print(m,"is Palindrome")
else:
print(m,"is not Palindrome")
```

Output

```Enter Number: 12321
12321 is Palindrome
```
