[英]How to delete a particular line from file in Python
def deleteEmployee(self,code,name):
with open("employee.data","r+") as file:
# data=file.readlines()
for num, i in enumerate(file,1):
print(i)
a=i[:len(i)-1]
if str(a)==str(code):
print("found at",num)
file.seek(num)
file.write("\n")
file.close()
我只想写一个文件处理代码。 在这里,我定义了删除函数,如果文件中存在特定代码但它不起作用,我想删除该函数。
此代码应该实现您想要的:
def deleteEmployee(self,code,name):
with open("employee.data","r+") as file:
new_content = ""
for num, line in enumerate(file,1):
print(line)
a=line[:-1]
if str(a)==str(code):
print("found at ",num)
new_content += "\n" #Adds newline instead of 'bad' lines
else:
new_content += line #Adds line for 'good' lines
file.seek(0) #Returns to start of file
file.write(new_content) #Writes cleaned content
file.truncate() #Deletes 'old' content from rest of file
file.close()
