Python–在 ASCII 范围内过滤字符串
原文:https://www . geesforgeks . org/python-filter-strings-in-ascii-range/
给定 ASCII 或字母范围，过滤特定范围内的字符串。
输入:test _ list =【“gfg”“is”“best”“for”“geeks”】，strt_asc，end_asc = 105，115 输出:【‘is’】 解释 : i 有 105，s 有 115，在 ASCII 值范围内。 输入:test _ list =[“gfg”，“is”，“best”，“for”，“geeks”]，strt_asc，end_asc = 100，115 输出:[“gfg”，“is”，“for”，“geeks”] 解释:包含范围字符的字符串。
在这种情况下，我们检查所有字符是否在给定的 ASCII 范围内，使用 order()计算，并相应地过滤字符串。
Python 3
# 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))
Output
The original list is : ['gfg', 'is', 'best', 'for', 'geeks']
Filtered Strings : ['is']
方法 2:使用过滤器()+λ+all()+order()
在本例中，我们使用 filter()和 lambda 函数执行过滤任务，order()和 all()的使用方式与上述方法类似。
Python 3
# Python3 code to demonstrate working of
# Filter Strings within ASCII range
# Using filter() + lambda + all() + ord()
# 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 = 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))
Output
The original list is : ['gfg', 'is', 'best', 'for', 'geeks']
Filtered Strings : ['is']
