Python noob，需要幫助改進方案

Question

我是python編程的新手，我需要一個能顯示當前CPU溫度的程序。我的CPU有4個內核，所以我做了以下程序。

#!/usr/bin/python 

import subprocess 
import re 

sensor_data = subprocess.check_output('/usr/bin/sensors') 

find_temp = re.search(r'Core 0:\s+\+([\d]+).*', sensor_data) 

if find_temp: 
    core_0_temp = find_temp.groups()[0] 
else: 
    core_0_temp = 0 

find_temp = re.search(r'Core 1:\s+\+([\d]+).*', sensor_data) 

if find_temp: 
    core_1_temp = find_temp.groups()[0] 
else: 
    core_1_temp = 0 

find_temp = re.search(r'Core 2:\s+\+([\d]+).*', sensor_data) 

if find_temp: 
    core_2_temp = find_temp.groups()[0] 
else: 
    core_2_temp = 0 

find_temp = re.search(r'Core 3:\s+\+([\d]+).*', sensor_data) 

if find_temp: 
    core_3_temp = find_temp.groups()[0] 
else: 
    core_3_temp = 0 

print core_0_temp, core_1_temp, core_2_temp, core_3_temp 

任何人都可以提出一些建議，如何改善這個計劃？

目前它的工作原理，但我能做些什麼來改善這個代碼？傳感器命令的

boby@fwhlin:~/utils/cpu$ ./cpu_temp 
49 48 48 46 
boby@fwhlin:~/utils/cpu$ 

結果給出如下

Answer 1

，你可以把它放在一個for循環，並使用字典/列表存儲值：

core_temps = {} 
for core in range(4): 
    find_temp = re.search(r'Core %d:\s+\+([\d]+).*' % core, sensor_data) 
    if find_temp: 
     core_temps[core] = find_temp.groups()[0] 
    else: 
     core_temps[core] = 0 
print core_temps 

Answer 2

我會做

#!/usr/bin/python 

import subprocess 
import re 

sensor_data = subprocess.check_output('/usr/bin/sensors') 

find_temps = re.finditer(r'Core (\d*):\s+\+([\d]+).*', sensor_data) 

temps = {} 
for find_temp in find_temps: 
    index, temp = find_temp.group(1, 2) 
    temps[index] = temp 

print temps 
for k in sorted(temps.keys()): 
    print k, temps[k] 
print 

這搜索全部Core XX:行，並將其放入字典中。
