python format float field width

Finally, the last character “f” of our placeholder stands for “float”. The string on which this method is called can contain literal text or replacement fields delimited by braces {}. Each value type can define its own “formatting mini-language” or interpretation of the format_spec.. You can invoke format function in one of the following ways: Single argument formatting. Below is the syntax to use it. You can use string formatting to format floating point numbers to a fixed width in Python.For example, if you want the decimal points to be aligned with width of 12 characters and 2 digits on the right of the decimal, you can use the following: >>>x = 12.35874 >>>print "{:12.2f}".format(x) 12.36 To convert float to two decimal places, you have to pass the third argument as ‘.3f‘. The field will be left-aligned within the available space. The decimal part of the number or the precision is set to 2, i.e. The f denotes fixed-point notation. However, you can convert float to 3 decimal places also. The empty string before the colon means “take the next provided argument to format()” – in this case the x as the only argument. You can use string formatting to format floating point numbers to a fixed width in Python. Python string format Width and Precision ... print '%10f' % 3.1415926 # Field width 10 print '%10.2f' % 3.1415926 # Field width 10, ... floatValue = 123456.789 print "Five digits after decimal in float %.5f" % floatValue The code above generates the following result. You have to read further to convert the float to 2 decimal places in Python. If not specified, then the field width will be determined by the content. Round Float to Three Decimal Places Using format() of Python. If the width field is preceded by a zero ('0') character, this enables zero-padding. Most built-in types support a common formatting mini-language, which is described in the next section. Python format function. The simplest case while calling the Python format function is to have a single formatter. Here are a few of the simple examples of the Python string formatting. '0' If the width field is preceded by a zero ('0') character, sign-aware zero-padding for numeric types will be enabled. The 10.4f part after the colon is the format specification. In this tutorial, you will learn how to convert a number into a floating-point number having a specific number of decimal points in Python programming language . ... '.format('Python Tutorial', 10) 'Python Tut' >>> Combining truncating and padding. If not specified, then the field width will be determined by the content. Each replacement field contains either the numeric index of a positional argument or the name of a keyword argument. This is the default for numbers. the number following the “.” in our placeholder. This is usually the default for strings. Preceding the width field by a zero (‘0’) character enables sign-aware zero-padding for numeric types. '>' The field will be right-aligned within the available space. Our float number 05.333 has to be formatted with 5 characters. The 10 is the total width of the field being printed, lefted-padded by spaces. Width¶ width is a decimal integer defining the minimum field width. For example, if you want the decimal points to be aligned with width of 12 characters and 4 digits on the right of the decimal, you can use the following: >>> x = 12.35874 >>> print "{:12.4f}".format(x) 12.3587 This is equivalent to an alignment type of '=' and a fill character of '0'. Formatting output using the format method : The format() method was added in Python(2.6). This is equivalent to a fill character of ‘0’ with an alignment type of ‘=’. The format_spec field contains a specification of how the value should be presented, including such details as field width, alignment, padding, decimal precision and so on. The format field in the above SF_INFO structure is made up of the bit-wise OR of a major format type (values between 0x10000 and 0x08000000), a minor format type (with values less than 0x10000) and an optional endian-ness value. 'width' is a decimal integer defining the minimum field width. The above example round the float to two decimal places.
