1. Programming to achieve 9*9 multiplication formulas

# 99 Multiplication of rectangles
For I in Range (1,10):
For j in Range (1,10):
Print ("%d*%d=%2d"% (i, J, I*j), end= "")
Print ("")

2. There are 1.3 billion people in our country. Annual growth rate of 0.8%, over 4 billion years

I=1
A=13
While a<40:
a=a* (1.008)
I=i+1
If a >=40:
Break
Print (i)

3. Programmed to calculate the average score for a class of 100 students and then count the number of people above the average

Count = 5
s = []
For I in range (count):
Print (i+1)
Name = input (' Name: ')
Score = input (' Score: ')
t = {}
t[' name '] = Name
t[' score ' = Int (score)
s + = [T]

#max = 0
#min = 0
All=0
sum = 0
For I in range (count):
Sum + = s[i][' score ']
a = Int (sum/count)
Print (a)

For I in range (count):

If a < s[i][' score ']:
all = all + 1
# if min > s[i][' score '):
# min = i
# sum +=s[i][' score ')
#print (' max: ' + s[max][' name '] + ' + str (s[max][' score '))
#print (' min: ' + s[min][' name '] + ' + str (s[min][' score '))
Print (' total: ' + str (all))
