In Python, we use the#character to initiate a comment. We use this for declaring single-line comments. Most programming languages support multi-line comments also. However, in Python, we can only have one-line comments. We cannot directly comment out multiple lines as comments in Python. Mul...
Watch a video course Python - The Practical Guide Another way to comment out multiple lines of code at once is to use triple quotes """. This can be used for both single or multiple line comments. """ This is a multi-line comment that can span multiple lines """ print("This is ...
Python Block Comment Method #2: Commenting Using Triple-Quoted String Literals An alternative method for commenting out multiple lines is to use triple-quoted string literals (''' ''' or """ """). While not officially block comments, these string literals are often used as such, especially...
how to plot multiple lines in python 如何plot multiple lines in Python 在数据可视化中,我们常常需要绘制多个线形。在Python中,有多种库可以帮助我们实现这一目标。本篇博客将会介绍如何使用matplotlib库来绘制多个线形。 首先,我们需要安装matplotlib库。如果你还没有安装这个库,可以使用以下命令进行安装: pip inst...
In Python, you have to comment out each individual line to do multiple lines or block comments: #Multiple #lines #of But there is one exception, although it’s a little messy. Python ignores things called “string literals,” which is anything that’s between triple quotes. So, you can ...
Here we are reading all the lines present inside the text file including the newline characters. Output: Now let’s see some more practical examples of reading a file. Reading a specific line from a File line_number = 4 fo = open(“C:/Documents/Python/test.txt”, ’r’) ...
Suppose you now like the idea of your earlier code being able to handle both exceptions in a single line. To do this, you decide to rewrite your code as follows: Python # multiple_exceptions.py try: first = float(input("What is your first number? ")) second = float(input("What is...
This will cause Python to ignore what you have written and instead treat it as if it were part of an existing statement. You can place your single-line comment anywhere on the line, or multiple lines if needed. Moreover, the only restriction is that there must be no whitespace between ...
You must be careful when using theexec()function because it implies some important security risks, especially if you’re using it for running external code. To learn more about this function, check outPython’sexec(): Execute Dynamically Generated Code. ...
my_multiple_line_string = """This is the first line This is the second line This is the third line""" To make sure we are on the same page, when we want Python to output a string to the console we use theprint()function. Theprint()function takes a value, tries to convert it ...
