1. len(): 返回字符串的长度。string = "Hello, World!"length = len(string)print(length) # 输出 13 2. upper(): 将字符串中的所有字符转换为大写。uppercase_string = string.upper()print(uppercase_string) # 输出 "HELLO, WORLD!"3. lower(): 将字符串中的所有字符转换为小写。lowercase_strin...
However, if you use the % operator and provide the values to interpolate as arguments to your logging functions, then you’ll optimize the interpolation process. The logging module will only interpolate those strings that belong to the current and higher logging levels. Consider the following examp...

Larn about Python string datatype and its functions. Learn how to format, align, find length and other such useful programs and exercises.
Beginning with Python 1.6, many of these functions are implemented as methods on the standard string object. They used to be implemented by a built-in module called strop, but strop is now obsolete itself. Public module variables: whitespace -- a string containing all characters considered whites...
Calling functions We can also call functions in f-strings. main.py #!/usr/bin/python def mymax(x, y): return x if x > y else y a = 3 b = 4 print(f'Max of {a} and {b} is {mymax(a, b)}') The example calls a custom function in the f-string. ...
Standard Library Functions Think of these as Python's pre-packaged gifts. They come built-in with Python, ready to use. These functions cover a wide range of common tasks such as mathematics,file operations, working withstrings, etc.

string data type. These functions let us easily modify and manipulate strings. We can think of functions as being actions that we perform on elements of our code. Built-in functions are those that are defined in the Python programming language and are readily available for us to use. ...
