打印类的所有属性和方法
利用dir(obj)方法获得obj对象的所有属性和方法名，返回一个list。
for item in dir(top_k_metergroup): #top_k_metergroup是某类的一个实例化对象 print(item)

python中更多种类的打印
1.print("." * 10） 是输出10个 "."
把每个字母相加输出就可以得到相应的字符串。
print(\"Mary had a little lamb.\")
print(\"Its fleece was white as {}.\" .format(\'snow\')) #将snow放入字符串的相应位置
print(\"And everywhere that Mary went.\")
print(\".\" * 10) # what\'d that do?
end1 = \"C\"
end2 = \"h\"
end3 = \"e\"
end4 = \"e\"
end5 = \"s\"
end6 = \"e\"
end7 = \"B\"
end8 = \"u\"
end9 = \"r\"
end10 = \"g\"
end11 = \"e\"
end12 = \"r\"
# watch that comma at the end. try removing it to see what happens
print(end1 + end2 + end3 + end4 + end5 + end6, end = \' \' ) # end = \' \' 为连接前后的成分，使其不换行
print(end7 + end8 + end9 + end10 + end11 + end12)
运行结果：
2.用了一个自定义的函数 formatter
其作用是：
<1>.取第1行定义的 formatter 字符串。
<2>.调用它的 format 函数,这相当于告诉它执行一个叫 format 的命令行命令。
<3>.给 format 传递4个参数，这些参数和 formatter 变量中的{}匹配，相当于将参数传递给了 format 这个命令。
<4>.在 formatter 上调用 format的结果是一个新字符串，其中的{}被4个变量替换掉了，这就是 print 现在打印出的结果。
formatter=\"{} {} {} {}\"
print(formatter.format(1,2,3,4))
print(formatter.format(\"one\",\"two\",\"three\",\"four\"))
print(formatter.format(True,False,False,True))
print(formatter.format(formatter,formatter,formatter,formatter))
print(formatter.format(
\"Try your\",
\"Own text here\",
\"Maybe a poem\",
\"or a song about fear\"
))
运行结果：
3.这个主要是讲定义的字符串可以直接打印出来
“\\n” 是换行符。
# Here\'s some new strange stuff, remember type it exactlyself. days = \"Mon Tue Wed Thu Fri Sat Sun\" months = \"\\nJan\\nFeb\\nMar\\nApr\\nMay\\nJun\\nJul\\nAug\" print(\"Here are the days: \", days) print(\"here are the months: \", months) print(\"\"\" There\'s something going on here. With the three double-quotes. we\'ll be able to type as much as we like. Even 4 lines if we want, or 5, or 6. \"\"\")
运行结果：
以上为个人经验，希望能给大家一个参考，也希望大家多多支持。
