Python程序去除字符串中K个长度的单词

给定一个字符串，编写一个Python程序来删除所有长度为 K 的单词。

例子：

Input : test_str = ‘Gfg is best for all geeks’, K = 3 
Output : is best geeks 
Explanation : Gfg, for and all are of length 3, hence removed.

Input : test_str = ‘Gfg is best for all geeks’, K = 2 
Output : Gfg best for all geeks 
Explanation : is of length 2, hence removed. 

方法 #1：使用split() + join() +列表推导+ len()

在这个过程中，每个单词使用 split() 进行拆分，然后使用 len() 检查长度，然后省略匹配 K。最后连接单词。

Python3

# Python3 code to demonstrate working of
# Remove K length words in String
# Using split() + join() + list comprehension + len()
  
# initializing string
test_str = 'Gfg is best for all geeks'
  
# printing original string
print("The original string is : " + (test_str))
  
# initializing K
K = 3
  
# getting splits
temp = test_str.split()
  
# omitting K lengths
res = [ele for ele in temp if len(ele) != K]
  
# joining result
res = ' '.join(res)
  
# printing result
print("Modified String : " + (res))

输出：

The original string is : Gfg is best for all geeks
Modified String : is best geeks

方法#2：使用filter() + lambda + split() + len() + join()

在此，我们使用 filter() + lamnda 执行过滤任务，其余功能与上述方法类似。

# initializing string
test_str = 'Gfg is best for all geeks'
  
# printing original string
print("The original string is : " + (test_str))
  
# initializing K
K = 3
  
# getting splits
temp = test_str.split()
  
# omitting K lengths
# filtering using filter() and lambda
res = list(filter(lambda ele: len(ele) != K, temp))
  
# joining result
res = ' '.join(res)
  
# printing result
print("Modified String : " + (res))

输出：

The original string is : Gfg is best for all geeks
Modified String : is best geeks
