Lesson2:Python:for Statement Simple Application

Sample1 Ball 1+2+3...+100 and

Sum=0

For I in Range (1,101):

Sum+=i

Print sum

1. Print if indented and sum+, the value of each sum+ will be printed
2. If print is shelf with for, it will only print the value of the final sum+ after the for loop has finished executing

Sample2:for loop application and bubble sort:

LIST=[10,12,14,19,20,22]

For I in range (1,len (list)):

For j in Range (0,len (list)-1):

If LIST[J]>LIST[J+1]:

LIST[J],LIST[J+1]=LIST[J+1],LIST[J]

Print List

1. Loop statement Sample2

list=["1", "2", "3", "4"

, "5", "6", "7"]

For I in list:

Print I

Note:

1. Whether it is an if statement or a for statement, you need to add ":" When you finish writing your judgment or condition, or you will get an error.
2. assignments, data type conversions, print, and so on are not required to add any punctuation
3. The list data type can be wrapped directly, not affected
