String format 2
tmp1.formt(‘Ham’, 200) ↓ Ham 200
In addition, as an example of format specification, write an example of format specification for displaying percentages. "12708" is the total population of Japan at the end of 2015, and "6381" is the number of employees (both units are 10,000). The working population ratio is displayed as a percentage, displaying two digits after the decimal point. In the second example, we put a comma in place of 1000. [Specify notation and insert] “{:.2%}”.format(6381/12708) ↓ 50.21%
“{:,}”.format(10000) ↓ 10,000
You can also specify the type of the replacement character string by putting alphabetic characters such as "c" and "d" at the end of the format specification part. "C" embeds the element as a character and "d" as a decimal integer.
