Python - 等距连续字符字符串

给定一个字符串列表，提取所有字符串，其连续字符在 ASCII 顺序上有共同的差异。

Input : test_list = [“abcd”, “egil”, “mpsv”, “abd”] 
Output : [‘abcd’, ‘mpsv’] 
Explanation : In mpsv, consecutive characters are at distance 3.

Input : test_list = [“abcd”, “egil”, “mpsw”, “abd”] 
Output : [‘abcd’] 
Explanation : In abcd, consecutive characters are at distance 1. 
 

方法 #1：使用列表理解+ all()

在这里，我们使用 all() 检查每个具有共同差异的字符，并使用列表理解来迭代字符串。

# Python3 code to demonstrate working of
# Equidistant consecutive characters Strings
# Using list comprehension + all()
  
# initializing list
test_list = ["abcd", "egil", "mpsv", "abd"]
  
# printing original list
print("The original list is : " + str(test_list))
  
# ord() used to get ASCII value
res = [sub for sub in test_list if all(ord(
    sub[idx + 1]) - ord(sub[idx]) == ord(sub[1]) - ord(sub[0]) for idx in range(0, len(sub) - 1))]
  
# printing result
print("Filtered Strings : " + str(res))

输出

The original list is : ['abcd', 'egil', 'mpsv', 'abd']
Filtered Strings : ['abcd', 'mpsv']

方法 #2：使用filter() + lambda + ord() + all()

在这里，我们使用 filter() 和 lambda函数执行过滤任务。 ord() 的任务是获得每个字符的 ASCII 等价物。

# printing result 
print("Filtered Strings : " + str(res))

输出

The original list is : ['abcd', 'egil', 'mpsv', 'abd']
Filtered Strings : ['abcd', 'mpsv']
