PYTHON原始思路问题遗留

import os
import shutil

print('HELLO GKOSON')
path1 ="/Users/Gong Jin Hua/Desktop/Merge/bootloader.hex"
path2 ="/Users/Gong Jin Hua/Desktop/Merge/application.hex"
path3 ="/Users/Gong Jin Hua/Desktop/Merge/merg.hex"


'''
try:
    f1 = open(path1, 'r')
    print(f1.read())
finally:
    if f1:
        f1.close()
'''
		
shutil.copyfile(path1,path3)  
print("复制完成：");

'''
f3 = open(path3, 'r')
lines = f3.readlines()
for line in lines:
	print(line)
f3.close()
'''
print("复制检测完成：");


f3 = open(path3, 'a')
print(f3.tell)
f3.seek(0,0)#--------------------这里总是崩溃
print(f3.tell)
f3.write("line")
f3.close()

input("合并完成：");
