Showing words in file that start with a specific letter [duplicate]
This question already has an answer here:
Iterator Object for Removing Duplicates in Python
2 answers
My code is able to show each word that starts with a specific letter from a text file, but I want it to not show duplicate words. Here is my code:
with open('text.txt','r') as myFile:
data=myFile.read().lower()
for s in data.split():
if s.startswith("r"):
print(s)
Like I said, my code does print the words but it shows duplicates. Thank you for helping

Use a set:
with open('text.txt', 'r') as myFile:
data = myFile.read().lower()
seen = set()
for s in data.split():
if s not in seen and s.startswith("r"):
seen.add(s)
print(s)

This is an optimized version the will read the file line by line without loading it all into memory:
seen_words = set()
with open('text.txt', 'r') as my_file:
for line in my_file:
for word in line.lower().split():
if word not in seen_words:
print(word)
seen_words.add(word)
