Three examples of "Python" teach you to write code

This article includes the Fibonacci sequence written in Python, the three-digit number of daffodils and the base code for hundred-dollar chickens:

(i) Fibonacci sequence:

‘‘‘

def Hanshu (n):

n_1 = 1

N_2 = 1

m = n

Sumn = 0

For a in range (1,m+1):

if m = = 1:

Return n_1

If m== 2:

Return n_2

Sumn = n_1 + n_2

N_2 = n_1

n_1 = Sumn

Print (Sumn,end = "")

Hanshu (20)

‘‘‘

Run the results for the above code:

(ii) Find out the number of daffodils within 1-1000:

def Hanshu (n):

Sumn = 0

m = n

For Dix in range (1,4):

m = m% 10

Sumn = Sumn + M * * 3

m = n//10

if Sumn = = N:

Print (N,end = "")

Def hanshu1 ():

For b in Range (1,1000):

Hanshu (b)

HANSHU1 ()

Run the results for the above code:

(three) hundred money to buy hundred chickens: Rooster 5 Yuan A, hen 3 yuan A, chicken 0.5 yuan A, 100 dollars to buy 100 chickens

Q: How many rooster hens and chickens should I buy, a total of several buying methods?

Set: Rooster for x only, hen for y only, chick for z only

x = 0

While x <= 100:

y = 0

While y <= 100:

z = 0

While Z <= 100:

If x + y + z = = + 5 * x +3 * y +0.5 * z = = 100:

Print (x, y, z)

z + = 1

Y + = 1

x + = 1

Run the results for the above code:
