Common examples of Python

Python language type: Strong-type language, dynamic language

Examples

1. Ask for the sum of the odd number within 100

The odd number can be printed by a number that is not equal to 0 for 2, or by using the For loop step

S=0

For I in range (1,100,2)

S+=i

Print (s)

2. Seeking the sum of the factorial of the

Use the For loop to set the range, accumulate in the loop

A=1
S=0
For I in Range (1,6):
A=a*i
S=s+a
Print (s)

3. Given a 5-digit number, reverse print

First to determine whether there is a 0 after the five-digit number, if there is not printing, if there are 0 in the middle can not skip. Example: 20500

a=20500

b=10

Flag=false #开关

For I in Range (a):

S=a%b

a=a//b

If flag or S: #第一次和第二次循环s =0,flag=false cannot enter, the third s=5 can enter, enter if after flag=true, so the back of 0 can also print

Print (s)

Flag=true

　　

4. Print the Fibonacci sequence within 100

You can use the while loop to implement

A=0

B=1

While b<100:

Print (b)

A,b=b,a+b

5. Finding the 101th Fibonacci sequence

A=0

B=1

For I in range (1,100):

if i = = 101:

Print (b)

A,b=b,a+b

6. Print 99 multiplication table

You can use the For loop to implement

For I in Range (1,10):

For j in Range (i,10):

S=i*j

Print (i, ' * ', j, ' = ', s,end= ' \ t ')
Print ()

or using the. Format implementation

For I in Range (1,10):
line = "
For j in Range (i,10):
line+= ' {0}*{1}={2:<4} '. Format (I,J,I*J)
Print (line)

7. Print Diamond

For I in Range ( -3,4):
L=-i If i<0 else I
Print (' *l+ ' * ' * (7-l*2))

8. Ask for prime numbers within 100000

Count=0 #计数
For I in Range (2,100000):
For j in Range (2,i-1):
If i%j==0:
Break
Else
Count + = 1
Print (Count,i)
