How to Count the Number of Characters in a String from a Python File?

Estimated read time 1 min read

To count the number of characters in a string from a Python file, you can use the built-in len() function in Python. Here’s an example code snippet:

# Open the file
file = open("file.txt", "r")

# Read the contents of the file into a string
file_contents = file.read()

# Count the number of characters in the string
num_chars = len(file_contents)

# Print the result
print("The file contains", num_chars, "characters.")

In the above code snippet, we first open the file using the open() function and the "r" mode to read the file. We then read the contents of the file into a string using the read() method of the file object.

Next, we use the len() function to count the number of characters in the string. Finally, we print the result using the print() function.

Note that this code assumes that the file contains only plain text characters, and not any special characters or formatting codes that may be present in a rich text document.
