What are the most common string operators used in Python and why they’re essential to know? It doesn’t take long when you begin programming in Python to work with strings and to start modifying these strings by using common operators. Here I’ll look at 5 of the most common string operators I use in my own Python code and how you can use them in your own code. 1. String Concatenation One of the first questions most new Python programmers seek to perform with strings is combining two or more together. This technique is known as string concatenation. ...
How do you remove the file extension from a path in Python? And can you do it using just one line of code?

What does [:-1] in Python actually do and why would you want to use it? [:-1] in Python is a slice operation used on strings or lists and captures all contents of the string or list except for the last character or element. Here are some examples demonstrating the operation of this code with strings: 1 2 3 >>> my_string = "Why?" >>> my_string[:-1] 'Why' As you can see from the simple code example above a variable my_string contains a string that ends with a question mark. By using the [:-1] slice operation it outputs the whole string except for the last character in the string. ...
How can you create a conditional format in Google Sheets based on the value from another cell or column regardless of whether that cell is on the same sheet or another?

Recently I had a simple requirement where I wanted to highlight a range of cells according to the MONTH() of a cell containing a date value. ...
What operator is used to raise a number to a power in Python? In Python the double asterisk operator ** is used to help calculate the exponent of a number raised to a power. This is done without a need to import the Python math library. For example, 2 to the power of 3 can be expressed using the double asterisk operator 2 ** 3, here the resulting output with the Python REPL: ...
What does the asterisk before a variable name mean in Python? For example, if I have a variable that contains a list of strings and the name of the variable is called my_list what does *my_list do?

How do you insert a line break into your HTML code? To insert a line break in HTML use the line break tag <br />. The line break tag is self-closing and doesn’t have a corresponding closing tag, like the paragraph tag does: <p></p>.
