How to rename files in python
In python, you can use the rename() function of the os package to rename files (directories). The syntax "os.rename(src_path,dst_path)" can rename the file of src_path to dst_path. Because rename() is a function provided by the os package, if you want to use this function, you need to introduce the os package first, with the syntax "import os".
Yes Rename files
Directly paste the code:
import os
srcFile = './actwork/linkFile/allExtLinks - 副本.txt'
dstFile = './actwork/linkFile/allExtLinks - copy.txt'
try:
os.rename(srcFile,dstFile)
except Exception as e:
print(e)
print('rename file fail\r\n')
else:
print('rename file success\r\n')Rename the files in the folder in order
When processing machine learning pictures, you need to put the pictures into different folders according to categories. In the folders, you also want to rename the pictures with increasing numbers to facilitate subsequent processing.
First, let’s take a look at python’s rename function:
os.rename(src,dst)
src: The directory name to be modifieddst: Modified directory name
If dst is an existing directory, OSError will be thrown.
Note: src and dst are both full path file names
First, let’s rename the folder
Use the simplest method to try it first
import os
def myrename(path):
file_list=os.listdir(path)
i=0
for fi in file_list:
old_name=os.path.join(path,fi)
new_name=os.path.join(path,str(i))
os.rename(old_name,new_name)
i+=1
if __name__=="__main__":
path="D:/test/121"
myrename(path)
We can see that the folders have been renamed in order
Slightly changed, it seems not so low
import os
def myrename(path):
file_list=os.listdir(path)
for i,fi in enumerate(file_list):
old_name=os.path.join(path,fi)
new_name=os.path.join(path,"N0."+str(i))
os.rename(old_name,new_name)
if __name__=="__main__":
path="D:/test/121"
myrename(path)
import os
def myrename(path):
file_list=os.listdir(path)
for i,fi in zip(range(len(file_list)),file_list):
old_name=os.path.join(path,fi)
new_name=os.path.join(path,"The."+str(i))
os.rename(old_name,new_name)
if __name__=="__main__":
path="D:/test/121"
myrename(path)The effect is the same:
## Next we Rename files
The above three methods can all be used, just need to be slightly modified. I will use the function enumerate as an example to demonstrate:
Create a text document first
Copy and paste a bunch of them for testing. Add a try-except to the function to prevent file renaming errors. Here The rename needs to be a file in the same format, otherwise an error will be reported:import os
def myrename(path):
file_list=os.listdir(path)
for i,fi in enumerate(file_list):
old_dir=os.path.join(path,fi)
filename="my"+str(i+1)+"."+str(fi.split(".")[-1])
new_dir=os.path.join(path,filename)
try:
os.rename(old_dir,new_dir)
except Exception as e:
print(e)
print("Failed!")
else:
print("SUcess!")
if __name__=="__main__":
path="D:/test/121"
myrename(path)
