One line if statement: ifa > b:print("a is greater than b") Try it Yourself » Short Hand If ... Else If you have only one statement to execute, one for if, and one for else, you can put it all on the same lin
To perform more complex checks, if statements can be nested, one inside the other. This means that the inner if statement is the statement part of the outer one. This is one way to see whether multiple conditions are satisfied. For example: num = 12 if num > 5: print("Bigger than 5...
In certain situations, theifstatement can be simplified into a single line. For example, number =10ifnumber >0:print('Positive') Run Code This code can be compactly written as number =10ifnumber >0:print('Positive') Run Code This one-liner approach retains the same functionality but in a...
The “OR” operator is utilized along with the “elif” statement. if either one or both of the conditions meets the given criteria, then the statement written inside the “elif” block will execute and show the result. Output: The above output shows the value that the number lies in the...
PEP 8: multiple statements on one line (colon) 解决方法:多行语句写到一行了,比如:if x == 2: print('OK')要分成两行写 PEP 8: line too long (82 > 79 characters) 解决方法:超过了每行的最大长度限制79 PEP 8: Simplify chained comparison ...
# for example when reading a large file, we only care about one row at a time def csv_reader(file_name): for row in open(file_name, 'r'): yield row # generator comprehension x = (i for i in range(10)) Iterator Iterator is like range(11), compare to list = [0,1,...,10...
笔记:本章没有介绍Python的某些概念,如类和面向对象编程,你可能会发现它们在Python数据分析中很有用。 为了加强Python知识,我建议你学习官方Python教程,https://docs.python.org/3/,或是通用的Python教程书籍,比如: Python Cookbook,第3版,David Beazley和Brian K. Jones著(O’Reilly) ...
