[Python] Three examples show you how to write code.

This article includes the Fibonacci series written in Python, the three-digit daffodils, and the basic code for buying a chicken for hundreds of dollars:

(1) Fibonacci series:

'''

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)

'''

For the above Code running result:

 

(2) Find out the daffodils within 1:

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 ()

For the above Code running result:

 

(3) buy a chicken for 0.5 RMB: Rooster for 5 yuan, hen for 3 yuan, chicken for 100 yuan, and 100 chicken for yuan

Q: How many rooster hens and chicks should I buy?

Set rooster to x, hen to y, and chicken to z

X = 0

While x <= 100:

Y = 0

While y <= 100:

Z = 0

While z <= 100:

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

Print (x, y, z)

Z + = 1

Y + = 1

X + = 1

For the above Code running result:
