如何删除 python 中以某些字符结尾的行？

Question

I have a.txt file which contains several characters in different position in lines. I want to read the.txt file and remove those lines end with ":"

The format of.txt file is:

Fruits&Vegetables:
Pearl 
Apple 
Orange 
Grapes: [Green] 
Cherry: [Red] 
Top 3 Anti-cancer vegetables:
Garlic 
Asparagus 
Broccoli 
Two other fruits:
Banana 
Dragon Fruit

I want to get this in a new dataframe

Fruits&Veges 
Pearl         
Apple         
Orange        
Grapes: [Green] 
Cherry: [Red] 
Garlic        
Asparagus     
Broccoli      
Banana        
Dragon Fruit 

I have tried to use.endwith, with following code.

import pandas as pd
fruit = pd.Series({'Fruits&Veges':'Pearl'}
file = open('fruit.txt','r')
for line in file:
    line = line.rstrip('\n')
    if line.endwith(':') == -1:
       s = line
    else: s = "title"
    row = {'Fruits&Veges':s}
    fruit = fruit.append(row, ignore_index=True)
    fruit = fruit[fruit['Fruits&Veges'] != 'title']

I simply want to get in a new dataframe

Fruits&Veges
Apple
Orange
Grapes: [Green]
Cherry: [Red]
Garlic
Asparagus
Broccoli
Banana
Dragon Fruit

The error message is 'str' object has no attribute 'endwith' , is there any smart way to do it quickly? Thank you.

Answer 1

It works with the following code this time...

import pandas as pd
fruit = pd.Series({'Fruits&Veges':'Pearl'}
file = open('fruit.txt','r')
for line in file:
    line = line.rstrip('\n')
    if line.endswith(':') == False:
       s = line
    else: s = "title"
    row = {'Fruits&Veges':s}
    fruit = fruit.append(row, ignore_index=True)
    fruit = fruit[fruit['Fruits&Veges'] != 'title']
