How to find the longest line from a text file in Python?
Using max() function: get the longest line from a text file in Python. We can use the max() function to find the line having the longest length by providing len as key to the function. print (max(open(‘name.txt’), key=len)) For the same example above we will run the code-Input. Hey! Welcome to the programming world of Python. Python is an
How to find the longest word in a text file?
#!/usr/bin/awk -f # Initialize two variables BEGIN { maxlength=0; maxword=0 } # Loop through each word on the line { for (i=1;i<=NF;i++) # Assign the maxlength variable if length of word found is greater.
Can you read a file line by line in AWK?
You (the OP) haven’t stated what “other processing” you have to do on the lines, or I could be more specific. But whatever that processing is, you can definitely do it in sed —or if that becomes too unwieldy, you could do it in awk with very little change to the above code:
How to change the length of a line in Python?
Here’s how I’d do it: After the script has run, check that the new file looks good, then move the old file to a backup dir and rename the new one x.txt. I’m afraid you’re doing it backwards: use len (line) instead of line (len).
How to get line count of large file cheaply in Python?
If one wants to get the line count cheaply in Python in Linux, I recommend this method: file_path can be both abstract file path or relative path. Hope this may help. How about this? How about this one-liner: This is a meta-comment on some of the other answers.
What are the bottlenecks for line count in Python?
The main bottleneck with line count is I/O access, as you need to read each line in order to detect the line return character, there is simply no way around. The second potential bottleneck is memory management: the more you load at once, the faster you can process, but this bottleneck is negligible compared to the first.
