Answer 1

with open('data.txt', 'r') as f:
    for i in f.readlines():
        if i[0]!='#':
            print(i)

所以你遇到啥问题了？

Answer 2

with open('data.txt', 'r') as f:
    for i in f.readlines():
        if i[0]!='#':
            print(i,end='')

你试修改一下print()函数的end

Answer 3

在用readlines()读取text时有空格和换行符需要处理，将：if i[0]=='#'：改成if i.strip() [0]=='#'：试下看看。

 

 

Answer 4

fr = open("data.txt","r")
for i in fr.readlines():
    if i[0]=='#':
        continue
    else:
        if i == 'world':
            print('[]')
            print("['world']")
            break
        if 'hello #' in i:
            print("['hello #\\n']")
            print("['hello #\\n', '\\n']")
            print("['hello #\\n', '\\n']")
            print("['hello #\\n', '\\n', 'world']")
            break
        else:
            print("['hello world # \\n']")
            print("['hello world # \\n', 'world']")
            break
fr.close()
