Python one line of content becomes multiple columns (one line becomes multiple columns)

Original content: 11111, 222222, 3333333333333, 44445, 555, 66666666666, 777777 I
want to turn a row into multiple columns.
This article is divided into two types: the
first type: split and then change to vertical rows.
The second type: directly turn text or numbers into Vertical line

1. Change to a vertical line after splitting

1.1 Method 1. Split first, then print

1.1.1 First sorted into a dictionary

f = open('D://hello.txt', 'rb')  # 以只读方式打开一个文件，获取文件句柄，如果是读的话，r可以不写，默认就是只读,
line = f.readlines()
for i in line:
    data = i.decode()#截取空格
    strlist = data.split('、')
    print(strlist)#取第一列

f.close()  

1.1.2 Traverse the dictionary again.

a=['11111', '222222', '3333333333333', '44445', '555', '66666666666', '777777']
for x in a:
    print(x)

1.2 Split + merge

You can combine 2 logics in one

f = open('D://hello.txt', 'rb')  # 以只读方式打开一个文件，获取文件句柄，如果是读的话，r可以不写，默认就是只读,
line = f.readlines()
for i in line:
    data = i.decode()#截取空格
    strlist = data.split('、')#字符之间用、隔开
    for X in strlist:
        print(X)
f.close()  # 关闭文件

Second, change the horizontal to vertical

s='开发测试说明书'
for i in s:
     print(i)

Three, summarize the application

The first type: mainly used for testing and writing document content.
The second type: mainly used for writing document cover.
