Python Program to Count the Occurrences of a Word in a Text File

#get file object reference to the file
file = open("C:\workspace\python\data.txt", "r")
#read content of file to string
data = file.read()
#get number of occurrences of the substring in the string
occurrences = data.count("python")
print('Number of occurrences of the word :', occurrences)

# Open the file in read mode 
text = open("sample.txt", "r") 
  
# Create an empty dictionary 
d = dict() 
  
# Loop through each line of the file 
for line in text: 
    # Remove the leading spaces and newline character 
    line = line.strip() 
  
    # Convert the characters in line to  
    # lowercase to avoid case mismatch 
    line = line.lower() 
  
    # Split the line into words 
    words = line.split(" ") 
  
    # Iterate over each word in line 
    for word in words: 
        # Check if the word is already in dictionary 
        if word in d: 
            # Increment count of word by 1 
            d[word] = d[word] + 1
        else: 
            # Add the word to dictionary with count 1 
            d[word] = 1
  
# Print the contents of dictionary 
for key in list(d.keys()): 
    print(key, ":", d[key])
