Python os.chdir()

Python中的os.chdir()方法用于将当前工作目录更改为指定路径。它只接受一个参数作为新目录路径。

语法:

os.chdir(path)

参数:

path:待修改目录的完整路径。

返回:不返回任何值

示例1

使用chdir()更改目录

# Python3 program to change the
# directory of file using os.chdir() method
 
# import os library
import os
 
# change the current directory
# to specified directory
os.chdir(r"C:\Users\Gfg\Desktop\geeks")
 
print("Directory changed")

输出:

Directory changed

示例2

使用os.getcwd()

要知道文件的当前工作目录，可以使用getcwd()方法。更改路径后，可以使用此方法验证当前工作目录的路径。

# import os module
import os
 
# change the current working directory
# to specified path
os.chdir('c:\\gfg_dir')
 
# verify the path using getcwd()
cwd = os.getcwd()
 
# print the current directory
print("Current working directory is:", cwd)

输出:

Current working directory is: c:\\gfg_dir

示例3

在更改目录时处理错误

# importing all necessary libraries
import sys, os
 
# initial directory
cwd = os.getcwd()
 
# some non existing directory
fd = 'false_dir / temp'
 
# trying to insert to false directory
try:
    os.chdir(fd)
    print("Inserting inside-", os.getcwd())
     
# Caching the exception   
except:
    print("Something wrong with specified\
          directory. Exception- ", sys.exc_info())
           
# handling with finally         
finally:
    print("Restoring the path")
    os.chdir(cwd)
    print("Current directory is-", os.getcwd())

输出:

Inserting inside- c:\gfg_dir\gfg
Something wrong with specified directory. Exception- 
Restoring the path
Current directory is- c:\gfg_dir\gfg
