Python os.path.normcase()

Python os.path.normcase() 方法在Python中用于规范化指定路径名的情况。在windows上，此方法将指定路径中的所有字符转换为小写，并将正斜杠(‘ / ‘)转换为反斜杠(‘ \ ‘)。此方法返回在Windows以外的操作系统上未更改的指定路径。

语法: os.path.normcase(path)

参数:

path:表示文件系统路径的类路径对象。

返回类型: 此方法返回一个字符串值，该值表示指定路径中的规范化情况。

示例1

使用 os.path.normcase() 方法(在Windows上)

# Python program to explain os.path.normcase() method
   
# importing os.path module
import os.path
 
# Path
path = r'C:\User\admin\Documents'
 
 
# Normalize the case of 
# characters in the specified path
norm_path = os.path.normcase(path)
 
# Print the normalized path 
print(norm_path)
 
# Path
path = '/hoMe/UseR/'
 
 
# Normalize the case of 
# characters in the specified path
norm_path = os.path.normcase(path)
 
# Print the normalized path 
print(norm_path)
 
# Path
path = r'C:\Users/Desktop'
 
# Normalize the case of 
# characters in the specified path
norm_path = os.path.normcase(path)
 
# Print the normalized path 
print(norm_path)

输出:

c:\\user\\admin\\documents
\\home\\user
c:\\users\\desktop

示例2

使用 os.path.normcase() 方法(适用于Windows以外的操作系统)

# Python program to explain os.path.normcase() method
   
# importing os.path module
import os.path
 
# Path
path = '/home/UseR/Documents'
 
 
# Normalize the case of 
# characters in the specified path
norm_path = os.path.normcase(path)
 
# Print the normalized path 
print(norm_path)
 
# Path
path = '/hoMe/UseR/'
 
 
# Normalize the case of 
# characters in the specified path
norm_path = os.path.normcase(path)
 
# Print the normalized path 
print(norm_path)
 
# os.path.norcase() method will return
# the specified path as it as
# on operating systems
# other than Windows
