は2つのコードを組み合わせて1つのコマンドとして機能します

Question

私は1つとして機能するために結合したい2つのコードに関する問題があります。私のプロジェクトは指紋を使ったクラス出席です。私はラズベリーパイでそれをやっています。マッチングが成功した後にスキャンされた指紋の画像をダウンロードする必要があります。今すぐ私は指と一致し、私のセンサーでスキャンされたイメージをダウンロードすることができ、私は別々に両方を行うことができますが、すぐにはできません。私がしたいのは、センサーに指紋を一致させ、指紋をもう一度スキャンして1つのコマンドで画像をダウンロードすることです。誰もがこれで私を助けることができますか？コードは以下の通りです：指紋を照合

：

import hashlib 
from pyfingerprint.pyfingerprint import PyFingerprint 


## Search for a finger 
## 

## Tries to initialize the sensor 
try: 
    f = PyFingerprint('/dev/ttyUSB0', 57600, 0xFFFFFFFF, 0x00000000) 

    if (f.verifyPassword() == False): 
     raise ValueError('The given fingerprint sensor password is wrong!') 

except Exception as e: 
    print('The fingerprint sensor could not be initialized!') 
    print('Exception message: ' + str(e)) 
    exit(1) 

## Gets some sensor information 
print('Currently used templates: ' + str(f.getTemplateCount()) +'/'+ str(f.getStorageCapacity())) 

## Tries to search the finger and calculate hash 
try: 
    print('Waiting for finger...') 

    ## Wait that finger is read 
    while (f.readImage() == False): 
     pass 

    ## Converts read image to characteristics and stores it in charbuffer 1 
    f.convertImage(0x01) 

    ## Searchs template 
    result = f.searchTemplate() 

    positionNumber = result[0] 
    accuracyScore = result[1] 

    if (positionNumber == -1): 
     print('No match found!') 
     exit(0) 
    else: 
     print('Found template at position #' + str(positionNumber)) 
     print('The accuracy score is: ' + str(accuracyScore)) 

    ## OPTIONAL stuff 
    ## 

    ## Loads the found template to charbuffer 1 
    f.loadTemplate(positionNumber, 0x01) 

    ## Downloads the characteristics of template loaded in charbuffer 1 
    characterics = str(f.downloadCharacteristics(0x01)).encode('utf-8') 

    ## Hashes characteristics of template 
    print('SHA-2 hash of template: ' + hashlib.sha256(characterics).hexdigest()) 

except Exception as e: 
    print('Operation failed!') 
    print('Exception message: ' + str(e)) 
    exit(1) 

は、画像をダウンロード：

import tempfile 
from pyfingerprint.pyfingerprint import PyFingerprint 


## Reads image and download it 
## 

## Tries to initialize the sensor 
try: 
    f = PyFingerprint('/dev/ttyUSB0', 57600, 0xFFFFFFFF, 0x00000000) 

    if (f.verifyPassword() == False): 
     raise ValueError('The given fingerprint sensor password is wrong!') 

except Exception as e: 
    print('The fingerprint sensor could not be initialized!') 
    print('Exception message: ' + str(e)) 
    exit(1) 

## Gets some sensor information 
print('Currently used templates: ' + str(f.getTemplateCount()) +'/'+ str(f.getStorageCapacity())) 

## Tries to read image and download it 
try: 
    print('Waiting for finger...') 

    ## Wait that finger is read 
    while (f.readImage() == False): 
     pass 

    print('Downloading image (this take a while)...') 

    imageDestination = tempfile.gettempdir() + '/fingerprint.bmp' 
    f.downloadImage(imageDestination) 

    print('The image was saved to "' + imageDestination + '".') 

except Exception as e: 
    print('Operation failed!') 
    print('Exception message: ' + str(e)) 
    exit(1)
