String Formatting

By You can format strings in a number of ways using Python. And Python, not being a lazy language, evaluates expressions before calling functions, so in your log. You may learn more about date formatting options in its tutorial: How to perform formatting for numbers using format function? The next step is to display the same data in fixed-point format. The conversion field causes a type coercion before formatting. If omitted, it returns the string representation of the object. It can have following values.

Anything else, which is not contained in curly braces will be literally printed, i. If it is an integer, it represents the index of the positional argument in args; if it is a string, then it represents a named argument in kwargs. Anything that is not contained in braces is considered literal text, which is copied unchanged to the output. Date objects are examples of such objects. We then passed 4 values into the str. If not specified, then the field width will be determined by the content.

. This will not , but instead limit the number of places shown after the decimal point. The column number is reset to zero after each newline occurring in the string. Use it if the order of your arguments is not likely to change and you only have very few elements you want to concatenate. Also, see the module for string functions based on regular expressions.

If given and not None, chars must be a string; the characters in the string will be stripped from the end of the string this method is called on. To use this module, we first import it via the import statement as follows: import datetime We can represent time values using the time class. We want to keep it like this. We can successfully do so by calling the strptime method. Strings starting with a sign are handled correctly.

As 453 consists only of 3 digits, the output is padded with 2 leading blanks. One can go as far as to say that this answer is not true. Justify a variable string expansion In the below example, we demonstrate the variable string expansion and justifies it. This value is used in the format function with various date directives for formatting. Therefore, it is often called string modulo or somethimes even called modulus operator, though it has not a lot in common with the actual modulo calculation on numbers.

Or to put it in other words: If the string modulo operator is applied to a string, it returns a string. If present, it specifies that the output will be prefixed by '0b', '0o', or '0x', respectively. The tab size defaults to 8. The default precision is 6. As we see, by default strings are left-justified within the field, and numbers are right-justified. It signifies whether to substitute a number or a string.

Consider the following points before executing the datetime code from datetime import date This line tells the Python interpreter that from the datetime module import the date class We are not writing the code for this date functionality alas just importing it for our use Step 2 Next, we create an instance of the date object. Forces padding to be placed between digit and the sign eg. In the parameters within the curly braces, we specified the index field number of the float and included the colon, indicated the size of the field number and included the full stop, wrote in the number of places after the decimal place, and then specified the conversion type of f. The decimal part of the number or the precision is set to 2, i. In Python, date, time and datetime classes provides a number of function to deal with dates, times and time intervals. Type It determines how data is displayed. You may also notice, the order is not important as calling in the placeholder than the sequence of the format function arguments.

Returntype : Returns a formatted string with the value passed as parameter in the placeholder position. Here is the Weekday Table which start with Monday as 0 and Sunday as 6 Day WeekDay Number Monday 0 Tuesday 1 Wednesday 2 Thursday 3 Friday 4 Saturday 5 Sunday 6 Weekday Number is useful for arrays whose index is dependent on the Day of the week. If given and not None, chars must be a string; the characters in the string will be stripped from the beginning of the string this method is called on. A format specification may be as simple as two curly brackets {} that specify a placeholder for data. Positive and negative infinity, positive and negative zero, and nans, are formatted as inf, -inf, 0, -0 and nan respectively, regardless of the precision. You see a Python Shell window open.
