Formatting floats without trailing zeros in python

Formatting floats without trailing zeros in python

You can format floats without trailing zeros in Python using the str.rstrip() method or using formatted string literals (f-strings). Here are two methods to achieve this:

Method 1: Using str.rstrip():

You can convert the float to a string and then use str.rstrip('0') to remove trailing zeros:

value = 12.3400
formatted_value = str(value).rstrip('0')
print(formatted_value)  # Output: '12.34'

In this example, str(value) converts the float to a string, and then rstrip('0') removes trailing zeros from the string representation.

Method 2: Using formatted string literals (f-strings):

You can use f-strings to format the float without trailing zeros:

value = 12.3400
formatted_value = f'{value:g}'
print(formatted_value)  # Output: '12.34'

In this example, f'{value:g}' formats the float using the "general" format, which removes trailing zeros. The :g specifier automatically determines whether to use fixed or exponential notation based on the magnitude of the number.

Both methods allow you to format floats without trailing zeros. Choose the one that fits your coding style and requirements.
