handle class: for instance
read file(article,assay,thesis,paper,ect...)ddd
file_read=open('d:jetbrians.compythonpycharmguide','r',encoding='UTF-8')
file.read()
print(file_r.read())
content=file_read.read(6）
print(content)
file_read.readline()
file_list=file_read.readlines()
for i in file_list:
print(i.strip)
strip method can delete the space between two line,implement line feed.
readlines method can read multiple-line and cellect all line cambine to one class [ list ]
list is a object.can use method read write .
The elements in file_read.readlines list can loop using 'for in file_read.readlines'
attribute properity
Write:
file_write=(open('d:jetbrians.compythonpycharminstruct','w',encoding='utf-8')
file_write('helle world ')
file_write('update 20190309')
file_close.close()
Append:
file_append=open('d:jetbrians.compythonpycharminstruct','a',encoding='utf-8')
file_append.write(' hello word')
line feed character
for instance (practice case):
number=0
for i in file_read.readlines():
number+=1
if number==6:
i=i.strip()+'poesy' \ i=' ',join((i.strip(),'iii'))
print(i.strip)
