Python – 水平和垂直字符串相互转换

给定一个字符串，如果水平则转换为垂直，反之亦然。

Input : test_str = ‘geeksforgeeks’
Output : g
e
e
k
s
Explanation : Horizontal String converted to Vertical.

Input : test_str = g
e
e
k
s
Output : ‘geeks’
Explanation : Vertical String converted to Horizontal.

方法 #1 : [水平到垂直] 使用循环 + “\n”

在此，我们在每个字符之后添加字符，以便每个元素在下一行呈现。

Python3

# Python3 code to demonstrate working of 
# Interconvert Horizontal and Vertical String
# using [Horizontal to Vertical] using loop + "\n"
  
# initializing string
test_str = 'geeksforgeeks'
  
# printing original String
print("The original string is : " + str(test_str))
  
# using loop to add "\n" after each character 
res = ''
for ele in test_str:
    res  += ele + "\n" 
      
# printing result 
print("The converted string : " + str(res))

输出

The original string is : geeksforgeeks
The converted string : g
e
e
k
s
f
o
r
g
e
e
k
s

方法 #2 : [垂直到水平] 使用 replace() + “\n”

在此，我们通过替换为空字符串来删除“\n”来执行转换任务。

Python3

# Python3 code to demonstrate working of 
# Interconvert Horizontal and Vertical String
# using [Vertical to Horizontal] using replace() + "\n"
  
# initializing string
test_str = 'g\ne\ne\nk\ns\nf\no\nr\ng\ne\ne\nk\ns\n'
  
# printing original String
print("The original string is : " + str(test_str))
  
# using replace() + "\n" to solve this problem
res = test_str.replace("\n", "")
      
# printing result 
print("The converted string : " + str(res)) 

输出

The original string is : g
e
e
k
s
f
o
r
g
e
e
k
s

The converted string : geeksforgeeks
