推导式

生成指定序列列表（程序生成）

lst = []
for i in range(1,6):
 lst.append(‘python_%d‘ % i)
print(lst)

结果：
F:\myPy\venv\Scripts\python.exe F:/myPy/test.py
[‘python_1‘, ‘python_2‘, ‘python_3‘, ‘python_4‘, ‘python_5‘]

#语法：
# [变量a for 变量a in 可迭代对象]
# return 可迭代对象
lst = [‘python_%d‘ % i for i in range(1,6)]
print(lst)

结果：
F:\myPy\venv\Scripts\python.exe F:/myPy/test.py
[‘python_1‘, ‘python_2‘, ‘python_3‘, ‘python_4‘, ‘python_5‘]
