輸出到文件

Question

代碼片段：

def after_equals(s): 
    return s.partition(' = ')[-1] 
for k,s in zip(keyword, score): 
    print after_equals(k) + ',' + after_equals(s) 

的代碼打印的輸出：

NORTH,88466 
GUESS,83965 
DRESSES,79379 
RALPH,74897 
MATERIAL,68168 

我需要輸出到文件中。請諮詢如何寫入文件。

Answer 1

以寫模式打開一個文件，並寫入一個字符串的文件，然後將其關閉：

f = file('myfile.txt','w') 
f.write(s) 
f.close() 

對於您的情況：

def after_equals(s): 
    return s.partition(' = ')[-1] 
f = file('myfile.txt','w') 
for k,s in zip(keyword, score): 
    f.write('%s,%s\n' % (after_equals(k), after_equals(s))) 
f.close() 

Answer 2

with open(filename, 'w') as out: 
    for k,s in zip(keyword, score): 
     print >> out, after_equals(k) + ',' + after_equals(s)
