How do you convert a string representing a percentage number into an actual number that can be used to perform calculations? To convert a string represented as a percentage number into an actual decimal number in Python use the built-in float() function after removing the percent symbol from the string and any other characters that prevent numeric conversion. Without purging from the original string the percent symbol you will get a ValueError as demonstrated below in the Python REPL: ...

How do you know if a string will convert to an integer in Python? There are 3 ways to check if a string will convert to an integer in Python and these methods are: use a try-catch on the int(string) operation or perform an operation on the string to remove all integers and see if anything is left – use either the regex library or the string.replace() method. Let’s look at each approach in a little more detail and use an example or two. ...

How do you format a cell that contains text like 1st Jan 2022 into a cell that Google Sheets can recognize as a date cell? There are certain types of date formats that can prevent the automatic import of data into Google Sheets into dates. One recent data type I had to deal with was where the day field was an abbreviated ordinal number (i.e. 1st, 2nd, 3rd, 4th… etc) and the month was an abbreviated month (eg. Jan, Feb, Mar… etc) and even the year was abbreviated too (eg. 2022 = 22, 2023 = 23, etc). ...

How do you capitalize the first letter of each word in a string using Python? To capitalize the first letter of every word in Python using one line of code enter the following: " ".join([x.capitalize() for x in my_string.split()]). Here is an example demonstrating how the code works in the Python REPL: 1 2 3 >>> my_string = "How long is a piece of string?" >>> " ".join([x.capitalize() for x in my_string.split()]) 'How Long Is A Piece Of String?' As you can see from the above example the output produces a string with each character capitalized. ...

How do you find the length of the string in Python without importing any libraries? To find the length of a string in Python use the built-in len() function, which takes one parameter that can be of data type string, bytes, tuple, list, range, or a collection (such as a dictionary, set, or frozen set). The len() function, when used on a string, will return the number of characters in that string. ...

Does Python have a ternary operator? If so, how does it work? A ternary operator, otherwise known as a conditional expression, is a simple if-else statement that is performed on one line of code to evaluate a condition. The value entered before the if clause is the True value returned, whereas the value after the else clause is the False value returned. The expression between the if and the else is the conditional clause that determines what value is returned. ...

What is the difference between using the logical operators and and or in Python? When using the and logical operator in Python all conditions in the statement need to be True for the entire expression to evaluate to True. If one condition evaluates to False then the entire expression evaluates to False. When using the or logical operator only one condition in the entire expression needs to evaluate to True for the entire expression to evaluate to True. If all conditions are False then the expression evaluates to False. ...

What does := mean and do in Python? Since Python version 3.8 the new assignment expression, also known as the walrus operator, enables developers the ability to assign a variable from the result of a function or operation and then have that assigned variable reused elsewhere in the code. One recent example in my code on this site was halving a string using Python. With this example I had the option of repeating my code multiple times in the simple one-liner I had created. Here is a copy of that code, and how it would have been handled without using the walrus operator: ...

How do you split a string into two equal halves using Python? To tackle this exercise you need to know how you’re going to operate on odd numbered string lengths. For example, how would you like your code to operate on the string halve. As it has 5 characters you’re going to have 5 possible solutions: hal and ve OR ha and lve ha, l and ve halve OR None The first solution just placed the middle character to either side giving the extra character to the first half or second half. ...
