Python|以不区分大小写的方式对字符串列表进行排序的方法

给定一个字符串列表，任务是以不区分大小写的方式对字符串进行排序。下面给出了一些解决任务的方法。
方法 #1：使用 casefold()

Python3

# Python code to demonstrate
# to sort list of
# strings in case insensitive manner
 
# Initialising list
ini_list = ['akshat', 'garg', 'GeeksForGeeks', 'Alind',
            'SIngh', 'manjeet', 'Munich']
 
# Sorting list in case sensitive manner
res1 = sorted(ini_list)
  
# Printing case-insensitive
print("Case-sensitive sorted list", str(res1))
 
# Sorting list in case-insensitive manner
res2 = sorted(ini_list, key = lambda s: s.casefold())
 
# Printing result
print("Case-insensitive sorted list", str(res2))

Python3

# Python code to demonstrate
# to sort list of
# strings in case insensitive manner
 
# Initialising list
ini_list = ['akshat', 'garg', 'GeeksForGeeks', 'Alind',
            'SIngh', 'manjeet', 'Munich']
 
# Sorting list in case sensitive manner
ini_list.sort()
  
# Printing case-insensitive
print("Case-sensitive sorted list", str(ini_list))
 
# Sorting list in case-insensitive manner
ini_list.sort(key = lambda x: x.lower())
 
# Printing result
print("Case-insensitive sorted list", str(ini_list))

输出：

区分大小写的排序列表 ['Alind', 'GeeksForGeeks', 'Munich', 'Singh', 'akshat', 'garg', 'manjeet']
不区分大小写的排序列表 ['akshat', 'Alind', 'garg', 'GeeksForGeeks', 'manjeet', 'Munich', 'Singh']

方法 #2：使用 lower()

Python3

# Python code to demonstrate
# to sort list of
# strings in case insensitive manner
 
# Initialising list
ini_list = ['akshat', 'garg', 'GeeksForGeeks', 'Alind',
            'SIngh', 'manjeet', 'Munich']
 
# Sorting list in case sensitive manner
ini_list.sort()
  
# Printing case-insensitive
print("Case-sensitive sorted list", str(ini_list))
 
# Sorting list in case-insensitive manner
ini_list.sort(key = lambda x: x.lower())
 
# Printing result
print("Case-insensitive sorted list", str(ini_list))

输出：
