Summarize the ways in which if is written in the Python learning process

This article summarizes the ways in which if is written in the Python learning process

Python instance learning small problems encountered, I change the topic need to display the results of each file, you can use the list and if statement to complete, the article finally is the original topic and the answer

One, if the way

A, procedures

#!/usr/bin/python
#-*-Coding:utf-8-*-

i = Int (input (' Net profit: '))
arr = [1000000, 600000, 400000, 200000, 100000, 0]
Rat = [0.01, 0.015, 0.03, 0.05, 0.075, 0.1]
R = 0
For IDX in range (0, 6):
If i > Arr[idx]:
R + = (I-arr[idx]) * RAT[IDX]

If arr[idx] = = 0:
Print (' <100000 ', ' gears ', (I-arr[idx]) * RAT[IDX])
Else
Print (Arr[idx], ' gears ', (I-arr[idx]) * RAT[IDX])
i = Arr[idx]

Print (' Total bonus: ', R)

D:\PythonScript\python\python.exe d:/pythonscript/456

B, procedures

#!/usr/bin/python
#-*-Coding:utf-8-*-

i = Int (input (' Net profit: '))
arr = [1000000, 600000, 400000, 200000, 100000, 0]
Rat = [0.01, 0.015, 0.03, 0.05, 0.075, 0.1]
R = 0
For IDX in range (0, 6):
If i > Arr[idx]:
R + = (I-arr[idx]) * RAT[IDX]

If arr[idx] = = 0:
Print (' <100000 ', ' gears ', (I-arr[idx]) * RAT[IDX])
Else
Print (Arr[idx], ' gears ', (I-arr[idx]) * RAT[IDX])
i = Arr[idx]

Print (' Total bonus: ', R)

Second, the way of the list

Program

#!/usr/bin/python
#-*-Coding:utf-8-*-


i = Int (input (' Net profit: '))
arr = [1000000,600000,400000,200000,100000,0]
Rat = [0.01,0.015,0.03,0.05,0.075,0.1]
FFF = [' Sixth gear ', ' V ', ' IV ', ' third gear ', ' second gear ', ' first gear ']
R = 0
For IDX in range (0,6):
If I>ARR[IDX]:
r+= (I-arr[idx]) *rat[idx]
Print (Fff[idx], (I-arr[idx]) *rat[idx])
I=ARR[IDX]
Print (' Total bonus: ', R)

Results

Ii. Original topics and solutions

Title: The bonuses awarded by the Enterprise are based on the profit commission. Profit (I) less than or equal to $100,000, the bonus can be raised by 10%, the profit is higher than $100,000, less than $200,000, the portion of less than 100,000 yuan by 10% commission, higher than the portion of 100,000 yuan, a commission of 7.5%, 200,000 to 400,000, higher than 200,000 yuan, can commission 5% ; Between 400,000 and 600,000 is higher than the portion of 400,000 yuan, can commission 3%, 600,000 to 1 million, higher than 600,000 yuan portion, can commission 1.5%, higher than 1 million yuan, the portion of more than 1 million yuan by 1% Commission, from the keyboard input month profit I, the total bonus should be issued?

Program Analysis: Please use the axis to demarcation, positioning. Note that the bonus definition should be defined as the growth integral type.

Program Source code:

Instance (Python 2.0+)

#!/usr/bin/python

#-*-Coding:utf-8-*-

i = Int (raw_input (' Net profit: '))

arr = [1000000,600000,400000,200000,100000,0]

Rat = [0.01,0.015,0.03,0.05,0.075,0.1]r = 0

For IDX in range (0,6):

If I>ARR[IDX]:

r+= (I-arr[idx]) *rat[idx]

Print (I-arr[idx]) *rat[idx]

I=arr[idx]print R

The result of the above example output is:

Net profit: 120000
1500.0
10000.0
11500.0
