Today, I'd like to share with you a Python txt file to join the dictionary and query method, has a good reference value, I hope to help you. Together follow the editor over to see it

As shown below:

dicFile = open('train_1.txt', 'r')# Open the data
print 'Starting to load data...'  
txtDict = {}#Build a dictionary
while True:  
    line = ()  
    if line == '':  
        break  
    index = ('\t')#Split by tab key
    key = line[:index]  
    value = line[index:]  
    txtDict[key] = value# Add to dictionary
()  
## Look up the dictionary
srcFile = open('', 'r')# Key to match
destFile = open('', 'w')# Write in the dictionary that matches
while True:  
    line = ()  
    if line == '':  
        break  
    index = (' ')  
    key = line[:index]  
    if txtDict.has_key(key):      
        (key)  
        (txtDict[key])         
    else:  
        (key)  
        ('\n')  
print 'All done!'
