Python - 过滤 ASCII 范围内的字符串

给定 ASCII 或字母范围，过滤在特定范围内找到的字符串。

Input : test_list = [“gfg”, “is”, “best”, “for”, “geeks”], strt_asc, end_asc = 105, 115 
Output : [‘is’] 
Explanation : i has 105, and s has 115, which is in range ASCII values.
Input : test_list = [“gfg”, “is”, “best”, “for”, “geeks”], strt_asc, end_asc = 100, 115 
Output : [‘gfg’, ‘is’, ‘for’, ‘geeks’] 
Explanation : Strings with range characters included. 
 

方法 #1：使用列表理解+ all() + ord()

在这里，我们检查所有字符是否在给定的 ASCII 范围内，使用 ord() 计算，并相应地过滤字符串。

Python3

# Python3 code to demonstrate working of
# Filter Strings within ASCII range
# Using list comprehension + ord() + all()
  
# initializing list
test_list = ["gfg", "is", "best", "for", "geeks"]
  
# printing original list
print("The original list is : " + str(test_list))
  
# initializing ASCII range
strt_asc, end_asc = 105, 115
  
# checking for all characters to be in ASCII range
res = [sub for sub in test_list if all(
    ord(ele) >= strt_asc and ord(ele) <= end_asc for ele in sub)]
  
# printing result
print("Filtered Strings : " + str(res))

输出

The original list is : ['gfg', 'is', 'best', 'for', 'geeks']
Filtered Strings : ['is']

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

在此，我们使用 filter() 和 lambda函数执行过滤任务，ord() 和 all() 的使用方式与上述方法类似。

strt_asc, end_asc = 105, 115
  
# checking for all characters to be in ASCII range
res = list(filter(lambda sub: all(ord(ele) >= strt_asc and ord(
    ele) <= end_asc for ele in sub), test_list))
  
# printing result
print("Filtered Strings : " + str(res))

输出

The original list is : ['gfg', 'is', 'best', 'for', 'geeks']
Filtered Strings : ['is']
