python遍历指定类型的文件

1、遍历以特定字符结尾的文件

root@PC1:/home/test# ls   ## 测试文件类型
out1.csv  out1.ped  out2.csv  out2.ped  out3.csv  out3.ped  test1.txt  test2.txt  test3.txt  traverse_file.py
root@PC1:/home/test# cat traverse_file.py
import os

for i in os.listdir():            ##此处的i是文件名形式的字符串，可以依据字符串的特征进行筛选
    if i.endswith(".ped"):        ## 遍历以.end结尾的文件
            print(i)
root@PC1:/home/test# python3 traverse_file.py
out1.ped
out2.ped
out3.ped

2、遍历以特定字符开头的文件

root@PC1:/home/test# ls              ## 测试文件
out1.csv  out1.ped  out2.csv  out2.ped  out3.csv  out3.ped  test1.txt  test2.txt  test3.txt  traverse_file.py
root@PC1:/home/test# cat traverse_file.py
import os

for i in os.listdir():
    if i.startswith("out"):         ## 遍历以out开头的文件
        print(i)
root@PC1:/home/test# python3 traverse_file.py
out3.csv
out1.ped
out2.csv
out1.csv
out2.ped
out3.ped
