如何從單個輸出打印多個txt文件

Question

我想寫每個組的不同文本文件;我該如何去做呢？目前它將所有內容寫入一個txt文件。

data = json.loads(output) 
print "===========================Example 1=======================================" 
for issue in data["issues"]: 
    print issue ['key'], issue['fields']['summary'] 

data = json.loads(output1) 
print"======================Example 2====================================" 
for issue in data["issues"]: 
    print issue ['key'], issue['fields']['summary'] 

data = json.loads(output2) 
print"====================== Example 3====================================" 
for issue in data["issues"]: 
    print issue ['key'], issue['fields']['summary'] 

data = json.loads(output3) 
print"======================Example 4====================================" 
for issue in data["issues"]: 
    print issue ['key'], issue['fields']['summary']  

data = json.loads(output4) 
print"======================Example 5====================================" 
for issue in data["issues"]: 
    print issue ['key'], issue['fields']['summary']  

硫雜是我已經解決了這個問題：

for issue in data["issues"]: 
    f.write(issue ['key']) 
    f.write(issue['fields']['summary']) 
    f.write('\n') 

它在列表中的每一行下單獨的文件寫的每一件事情。

你只是在你的例子中打印，而不是寫入文件。 另外，如果有100個輸出，你會怎麼做？

簡化的解決方案的僞代碼示例：

output1 = {...} 
outputs = (output1, output2, output3) 

for index, output in enumerate(outputs): 
    filename = 'output_data_{0}'.format(index) 

    #this will write file in directory relative to script location 
    with open(filename, 'w') as f: 
     f.write('Example {0}:\r\n'.format(index)) 

     for issue in data["issues"]: 
      # assumes issue is of type dict 
      # assumes issues has appropriate keys 
      # assumes values are of string type 
      key = issue['key'] 
      summary = issue['fields']['summary'] 

      f.writelines((key, summary, "\r\n",)) 

對於Python文件對象文檔：

而且，請注意，這個解決方案不是類型安全，應小心以確保將字符串傳遞給文件對象的寫入方法。
