Python Loop Small Example

1. Achieve 1-100 of all and

sum = 0

forIinchxrange(1,101):

Sum+=i

Print (sum)

Results:

5050

2. Achieve 1-500 of all odd and

sum = 0

forIinchxrange(1,501):

if i%2 = = 1:

Sum+=i

Print (sum)

Results:

62500

3. Ask for 1+ 2! + 3! + 4! + ... 20! and the

sum = 0

Chengji = 1

forIinchxrange(1, +):

Chengji=chengji*i

sum = sum + Chengji

Print (Chengji)

Print (sum)

Results:

2432902008176640000

4. Sort the specified list [2,32,43,453,54,6,576,5,7,6,8,78,7,89]

list1= [2, +, +,453, Wu,6,576,5,7,6,8, +,7, the]

List1.sort ()

Print (List1)

List1.reverse ()

Print (List1)

Results:

[2, 5, 6, 6, 7, 7, 8, 32, 43, 54, 78, 89, 453, 576]

[576, 453, 89, 78, 54, 43, 32, 8, 7, 7, 6, 6, 5, 2]
