Although this method is still a valid way to format strings, it can lead to errors and decreased clarity in code when you're dealing with multiple variables. Either of the other two formatting options described
F-strings can span multiple lines, making it easy to format longer messages or blocks of text. You can use triple quotes to create a multiline f-string and embed variables or expressions on any line. main.py #!/usr/bin/python name = 'John Doe' occupation = 'gardener' age = 34 msg ...
To format values in an f-string, add placeholders{}, a placeholder can contain variables, operations, functions, and modifiers to format the value. Example Add a placeholder for thepricevariable: price =59 txt = f"The price is {price} dollars" ...
Before Python 3.6, you had two main tools for interpolating values, variables, and expressions inside string literals:The string interpolation operator (%), or modulo operator The str.format() methodYou’ll get a refresher on these two string interpolation tools in the following sections. You’...
You can use f-strings and the string formatting mini-language to format the values that you interpolate into your strings in multiple ways. To illustrate, say that you want to write a Python function to build a grades report for your students. The student data is in a dictionary that looks...
>>> str='string learn' >>> dir(str) ['__add__', '__class__', '__contains__', '__delattr__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__getnewargs__', '__getslice__', '__gt__', '__hash__', '__init__...
7 8 Public module variables: 9 10 whitespace -- a string containing all characters considered whitespace 11 lowercase -- a string containing all characters considered lowercase letters 12 uppercase -- a string containing all characters considered uppercase letters 13 letters -- a string containing ...
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
python的string模块 1.字符串属性方法操作: 1.>字符串格式输出对齐 >>> str = "Python stRING" >>> print str.center(20) #生成20个字符长度,str排中间 Python stRING >>> print str.ljust(20) #生成20个字符长度,str左对齐 Python stRING >>> print str.rjust(20) #生成20个字符长度,str右对齐 Pyt...
That is fine—we can include multiple%sas placeholders in the string and provide the variables in a parentheses after the%sign. This is illustrated the following code: icecream_selection=['strawberry','vanilla','chocolate']jelly_selection=['lime','orange','strawberry','raspberry','blackcurrant'...
