The f-strings have thefprefix and use{}brackets to evaluate values. Format specifiers for types, padding, or aligning are specified after the colon character; for instance:f'{price:.3}', wherepriceis a variable name. Python string formatting The following example summarizes string formatting opt...
F-strings are string literals prefixed with 'f' or 'F' that contain expressions inside curly braces {}. These expressions are evaluated at runtime and then formatted using the __format__ protocol. Unlike traditional string formatting methods, f-strings provide a more straightforward and readable...
# the above formatting can also be done by using f-Strings # Although, this features work only with python 3.6 or above. print(f"I love {'Geeks'} for \"{'Geeks'}!\"") # using format() method and referring # a position of the object print(f"{'Geeks'} and {'Portal'}") 1. ...
1、python 中的 f-string 是什么? 在Python 的历史中,字符串格式化的发展源远流长。在 python 2.6 之前,想要格式化一个字符串,你只能使用 % 这个占位符,或者string.Template 模块。不久之后,出现了更灵活更靠谱的字符串格式化方式: str.format 方法。

The 0 flag causes padding with "0" characters instead: Python >>> "%05d" % 123 '00123' >>> "%08.2f" % 1.2 '00001.20' The 0 flag can be used with all the numeric conversion types: d, i, u, x, X, o, f, F, e, E, g, and G....
print("Binary: {0:b} => {0:#b}".format(3))print("Large Number: {0:} => {0:,}".format(1.25e6))print("Padding: {0:16} => {0:016}".format(3))# Binary: 11 => 0b11# Large Number: 1250000.0 => 1,250,000.0# Padding: 3 => 0000000000000003 ...

Combining numeric format specifiers Multiple format specifiers can often be combined. For example if you wanted a number represented as hexadecimal with padding to make it 2-digits long, you could combine02dwithxto make02x: >>>bits=13>>>print(f"{bits:02x}")0d ...
