Iterate through only a couple of files in a folder

Python

Currently I loop through all the files in the folder by using:

for eachFile in os.listdir(savePath):

Whats a quick way to look at the only the first 50 files? I am troubleshooting my program and looking at all ~2000 files in the folder takes too much time to loop through.

if I can reduce the number of files I look at I can debug much faster. The following feels clunky... any suggestions on making this ultra efficient? Thank you!

g = []
for eachFile in os.listdir(savePath):
    j = eachFile.strip(".tx")
    g.append(j)

For x in range(0,50):
    

    #Created a list for each file
    w = list(reversed(list(open(savePath + '/' + g[x]))))
