Python has many ways in which to comment on multiple lines of Python. One possibility is to feature # at the beginning of every line. ginger eight and therefore the larger a part of the community opt to comment out like:
# this can be a comment
# with multiple lines
instead of:
“””
This is a comment
with multiple lines
“””
Multiline comments in Python will begin with ”’ and finish with ”’. Multiline comment is made just by putting them within triple-quoted strings:”’/””” and ”’/”””.
Both examples have valid syntax in Python.
How to comment out multiple lines in Python
In Python, there’s a special image for comments that is #. Some languages, such as Java, have local support for multi-line comments.
Python multiline comment would seem like to:
# This
# is a
# multi-line
# comment
This is the default comment for many standard Python days like PyCharm, Sublime, VS Code.
Python multiline comments and docstrings
Guido van Rosem (creator of Python, Python BDFL) once posted a “Pro-Tip” of Python comments in multi-lines:
According to this tip, you’ll be able to do comments during this way:
“””line1
line2
line3″””
”’line1
line2
line3”’
What is a docstring? the primary statement in a very category, method, function, or module definition that may be a string is termed a docstring. Example:
def is_palindrome(word):
“””Check if the word is a palindrome.”””
str(word) == str(word)[::-1]
Note 1: even though a docstring contains only 1 line, triple quotes ought to be used as a result of it’s easier to expand it within the future.
Note 2: For one-liners, it’s suggested the quotes get on constant line because of the comment.
Multiline docstrings example
Descriptive multiline docstrings facilitate understanding and maintaining the code. Here you’ll be able to realize AN example for such:
def complex(real=0.0, imag=0.0):
“””Form a complex number.
Keyword arguments:
real — the real part (default 0.0)
imag — the imaginary part (default 0.0)
“””
if imag == 0.0 and real == 0.0:
return complex_zero
…
Many and organizations are exploiting this type of comment when they want to get good documentation.
Multi-line shortcuts for Python and IDEs are very popular
For commenting many lines on a preferred day you’ll be able to use consequent shortcuts.
First, you would like to pick the lines then press:
- Pycharm – CTRL + / – comment / uncomment
- Eclipse – CTRL + /- comment / uncomment
- Sublime – CTRL + /- comment / uncomment
- Atom – CTRL + /- comment / uncomment
- IDLE – CTRL + ALT + 3 – comment, CTRL + ALT + 4 – uncomment
- Notepad++ – CTRL + Q – comment / uncomment
- vim – CTRL + Q / kbd>CTRL + V – comment / uncomment
- VS Code – CTRL + / – comment / uncomment
Note: If you wish to feature a multi-line docstring then you’ll be able to use completely different combinations:
- Pycharm – Alt + Enter function and select Insert text string stack
- VS Code – Alt + Shift + A – comment / uncomment
PyCharm comment multiple lines
Pycharm comment shortcut
Here are the shortcuts to commenting on the various lines in Python and Pie Charm:
- Windows or Linux: Ctrl + /
- Mac OS: Command + /
Pycharm comment out multiple lines
To touch upon many lines of code within the Pycharm follow consequent steps:
- Select the code lines
- Menu
- Code
- Comment with Line Comment
- Windows or Linux: Ctrl + /
- Mac OS: Command + /
result:
# time.sleep(50 / 1000) # 50 ms
# time.sleep(5) # 5 secs
# time.sleep(60) # 1 min
Pycharm uncomment multiple lines
To uncomment commented lines in PyCharm you’ll be able to roll in the hay by constant steps as commenting:
- Select the code lines
- Menu
- Code
- Comment with Line Comment
- Windows or Linux: Ctrl + /
- Mac OS: Command + /
time.sleep(50 / 1000) # 50 ms
time.sleep(5) # 5 secs
time.sleep(60) # 1 min
Note: If you are attempting to comment mixed lines code and comments then
- first press Ctrl + / will comment all lines (add second mark # # in front of commented lines)
- the second Ctrl + / will uncomment all lines (only the first comment)
Before
# time.sleep(50 / 1000) # 50 ms
# time.sleep(5) # 5 secs
time.sleep(60) # 1 min
time.sleep(60 * 60) # 1 hour
After
# time.sleep(50 / 1000) # 50 ms
# # time.sleep(5) # 5 secs
# time.sleep(60) # 1 min
# time.sleep(60 * 60) # 1 hour
Python takes away all comments from a project with regex finders
You can remove all Python comments from your Python (Pycharm) project:
- open replace Ctrl + R
- check regex
- use
- single-line comment
.*#.*\n
* docstring line comment
“””.*”””
* docstring with new lines inside
([^\(\.]”””[^\(]*)”””
- replace all with nothing
