文件存儲與異常

1、打開關閉文件

import os if os.path.exists('sketch.txt'):the_file = open('sketch.txt')print(the_file.readline(),end=' 'the_file.close() else:print('the data is missing')

2、split函數

for each_line in data:if not each_line.find(':') == -1(role,line_spoken) = each_line.split(':',1) #分成兩部分

3、異常處理

try:the_file = open('sketch.txt')print(the_file.readline(),end=' ' except IOError:print('the data is missing') finally:the_file.close()try:with open ('it.txt',"w") as data:print("aag",file = data) except IOError as err:print("File error:" + str(err) )

4、strip函數

(role,line_spoken) = each_line.split(':',1) line_spoken = line_spoken.srep() #從字符串去除不想要的字符

5、寫入文件

out = open("data.out",'w') print("NOR iii",file = out) out.close()

6、保存文件

import pickle with open('mydata.pickle','wb') as msdpickle.dump([1,2,'t'],msd)with open('mydata.pickle','rb') as mrdmlist = pickle.load(mrd)print(mlist) 《新程序員》：云原生和全面數字化實踐50位技術專家共同創作，文字、視頻、音頻交互閱讀
