文件操作
文件操作，涉及到对文件读、写、执行等
打开一个文件open()
打开一个文件：
file = open("/Users/haowenchao/Downloads/python/file/hello.txt","r")
file1Str1=list()
file1Str2=list()
file1Str3=list()
print(type(file1Str1))
count = 1
print("#####################################################")
for eachline in file:
if(count==1):
if(eachline[:6]=="======"):
print("count=" + str(count))
count +=1
continue
else:
file1Str1.append(list(eachline))
if(count==2):
if(eachline[:6]=="======"):
print("count=" + str(count))
count +=1
continue
else:
file1Str2.append(list(eachline))
if(count==3):
print("count=" + str(count))
file1Str3.append(list(eachline))
file.close()
print(file1Str1)
print("-----------------------------------------------------")
print(file1Str2)
print("-----------------------------------------------------")
print(file1Str3)
print("-----------------------------------------------------")
print("#####################################################")
------------------------------------------------------------------------------------------------------------------------------------------
改进版：
file = open("/Users/haowenchao/Downloads/python/file/hello.txt","r")
file1 = open("/Users/haowenchao/Downloads/python/file/file1.txt","w")
file2 = open("/Users/haowenchao/Downloads/python/file/file2.txt","w")
file3 = open("/Users/haowenchao/Downloads/python/file/file3.txt","w")
file1Str1=list()
file1Str2=list()
file1Str3=list()
print(type(file1Str1))
count = 1
print("#####################################################")
for eachline in file:
if(count==1):
if(eachline[:6]=="======"):
print("count=" + str(count))
count +=1
continue
else:
file1Str1.append(list(eachline))
if(count==2):
if(eachline[:6]=="======"):
print("count=" + str(count))
count +=1
continue
else:
file1Str2.append(list(eachline))
if(count==3):
print("count=" + str(count))
file1Str3.append(list(eachline))
file.close()
print(file1Str1)
file1.write(str(file1Str1));
print("-----------------------------------------------------")
print(file1Str2)
file2.write(str(file1Str2));
print("-----------------------------------------------------")
print(file1Str3)
file3.write(str(file1Str3));
print("-----------------------------------------------------")
print("#####################################################")
file1.close()
file2.close()
file3.close()
