In Python, “for-loop” is widely used to iterate over a sequence, list, or any object. For loop avoids multiple usages of code lines to make the program concise and simple. The “One line for loop” is also the form of “for loop” which means that a complete syntax of “for loop...
# 使用列表推导式生成九九乘法表multiplication_table = [f"{j} x {i} = {i * j}" for i in range(1, 10) for j in range(1, i+1)]# 打印九九乘法表for line in multiplication_table: print(line)这段代码中，外层列表推导式遍历i从1到9，内层列表推导式遍历j从1到i（包括i），这样就可以生...
In Python, we use indentation (spaces at the beginning of a line) to define a block of code, such as the body of a loop. For example, languages = ['Swift', 'Python', 'Go'] # start of the loop for lang in languages: print(lang) print('---') # end of the for loop print...

for fruit in fruits: print(fruit) 在这个例子中 ,fruits列表就是一个可迭代对象 ,Python内部会创建一个迭代器对象来依次取出每个元素。 1.1.2 生成器概念与yield关键字 生成器是一种特殊的迭代器,但它不是通过定义__iter__()和__next__()方法来实现 ,而是使用def关键字定义一个包含yield语句的函数。当调...
