Example 1: Using a for loop
The content of the file my_file.txt
is
honda 1948 mercedes 1926 ford 1903
Source Code
def file_len[fname]:
with open[fname] as f:
for i, l in enumerate[f]:
pass
return i + 1
print[file_len["my_file.txt"]]
Output
3
Using a for loop, the number of lines of a file can be counted.
- Open the file in read-only mode.
- Using a for loop, iterate through the object
f
. - In each iteration, a line is read; therefore, increase the value of loop variable after each iteration.
Example 2: Using list comprehension
num_of_lines = sum[1 for l in open['my_file.txt']]
print[num_of_lines]
Output
3
- Open the file in read-only mode.
- Using a for loop, iterate through
open['my_file.txt']
. - After each iteration, return 1.
- Find the sum of the returned values.
Project description
Pygount is a command line tool to scan folders for source code files and count the number of source code lines in it. It is similar to tools like sloccount and cloc but uses the pygments package to analyze the source code and consequently can analyze any programming language supported by pygments.
The name is a combination of pygments and count.
Pygount is open source and distributed under the BSD license. The source code is available from //github.com/roskakori/pygount.
Quickstart
For installation run
$ pip install pygount
To get a list of line counts for a projects stored in a certain folder run for example:
$ pygount ~/projects/example
To limit the analysis to certain file types identified by their suffix:
$ pygount --suffix=cfg,py,yml ~/projects/example
To get a summary of each programming language with sum counts and percentage:
$ pygount --format=summary ~/projects/example
As an example here is the summary output for pygount's own source code:

Plenty of tools can post process SLOC information, for example the SLOCCount plug-in for the Jenkins continuous integration server.
A popular format for such tools is the XML format used by cloc, which pygount also supports and can store in an output file:
$ pygount --format=cloc-xml --out=cloc.xml ~/projects/example
To get a short description of all available command line options use:
$ pygount --help
For more information and examples read the documentation chapter on Usage.
