We have seen how to solve the Remove Zeros From Decimal Python with various examples. How do I remove zeros from a decimal in Python?Remove trailing zeros from decimal in Python #
How do you remove zeros after a decimal point?Remove trailing zeros from decimal numbers by Format Cells
How do I remove zeros in Python?Use str. strip(chars) on a string with "0" as chars to remove zeros from the beginning and end of the string. How do I remove decimal digits in Python?To remove the decimal from a number, we can use the int() method in Python. The int() method takes the number as an argument and returns the integer by removing the decimal part from it. It can be also used with negative numbers.19-Aug-2021 How do you round decimals in Python?Round() Round() is a built-in function available with python. It will return you a float number that will be rounded to the decimal places which are given as input. If the decimal places to be rounded are not specified, it is considered as 0, and it will round to the nearest integer.10-Sept-2022 How do you truncate to 2 decimal places in Python?Python's round() function requires two arguments. First is the number to be rounded. Second argument decides the number of decimal places to which it is rounded. To round the number to 2 decimals, give second argument as 2.02-Mar-2020 How do you remove floating trailing zeros?To remove the trailing zeros from a number, pass the number to the parseFloat() function. The parseFloat function parses the provided value, returning a floating point number, which automatically removes any trailing zeros.23-Oct-2021 How do you get rid of leading zeros?How do you get rid of decimal points?To convert a decimal to a rational number follow these steps: Step 1: Write down the decimal divided by 1. Step 2: Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.) How do I remove all zeros from a list in Python?We can use the Python filter() function to extract all the items in a list of numbers which do not equal 0 and remove the zeros from a list.09-Feb-2022 In your Python journey, you will encounter situations where you have a string denoting a floating point number but which might contain extraneous trailing zeros. For instance, you might have a string such as “314.560” or “123.4000” and you desire to remove the trailing zeros, so that we obtain “314.56” or “123.4”. Here are five ways to remove trailing zeros from a Python string. Method 1: Use a for loopWe can write a vanilla for loop going through the string in reverse and remove trailing zeros as we encounter them. For this purpose we create a variable to keep track of whether we have encountered the first non-zero character and once we do so we no longer remove zeros. For instance, a string such as “314.50600” should be converted to “314.506”, not “314.56”.In the code below, mystring contains the original string with potentially trailing zeros and answer contains the modified string, with zeros removed from the end. The variable “inside” keeps track of whether we have crossed the trailing zeros portion of the string. Note also that we use the pass statement because we have an empty block in our if..else statement.To keep the notation simple we reverse the string for use in an iterator and then re-reverse it (using string slicing operators) after the zeros are removed.The output is, as expected:Method 2: Use string slicing operators in a while loopThe above code can be made more succinct using Python’s string slicing operators in a while loop. For instance, consider the following code:This will output as before:Method 3: Use the rstrip() methodThe rstrip() method operates on a given string and returns a string with trailing characters removed (and you can specify which trailing characters you are interested in).In the above code rstrip works on the mystring variable and removes trailing characters where the trailing character is specified to be 0.This code outputs:See how simple the code is? This is because somebody has done the hard work of writing the logic we need inside the rstrip() method.Method 4: Recursive removal of trailing zerosIn this method we write our own function that recursively calls itself to remove trailing zeros. If there are no zeros it simply returns its input as the output.In the above we use the endswith() method to check if the string has a trailing zero. Note that this will only check if there is a single trailing zero and will not be able to distinguish between one or two (or more) trailing zeros. Thus, as soon as a trailing zero is detected, we recursively call the function with the string with that last character removed. If no trailing zero is detected, the given string is simply returned (the base case for the recursion).If we use this function like so:we will get:Method 5: Use float() and str() casting functionsThe built-in float() function converts a string to a float and str() converts a float (or an integer) to a string. Implicitly float() helps remove trailing zeros. Thus we can create a simple routine to remove trailing zeros with:This will output:Note that this approach will also work if you have leading zeros. Thus the code:yields:What will happen with the earlier methods? Will they also work with leading zeros? Explore it and see if you need to make any modifications. What happens if we give a negative integer, such as “-00314.50600”? Which methods work? We will leave it as an exercise for you to try them out and modify them as/if necessary.If you enjoyed this blogpost, checkout our post on removing leading zeros in a Python string.
