用python输出世界你好_"Hello World!" 我的python之旅开始了~

本人测试萝卜出生，测试做了快两年了，越来越觉得测试工作的重复性与枯燥性不能适应，决定转转开发，首当其冲就瞄上了python，不用多说了，直接开始吧！

首先肯定是输出与输入：

print("Hello World！")#这是基于一种仪式吧，对世界问好！

input("name:")

深层次输出：

name = input("name:")

age = input("age:")

job = input("job:")

mm = input("mm:")

ww = '''-------of where {_name}--------

name:{_name},

age:{_age},

job:{_job},

mm:{_mm}'''.format(_name=name,_age=age,_job=job,_mm=mm)

print(ww)

列表基础：

names = ["zhangyang","lidongmei",["fs","wz"],"wangza","yaoming"]print(names[0],names[1])print(names[:2])#切片

print(names[1:3])#切片

print(names[-3:])#切片

print(names[-1])#切片

names.append("liyang")#追加

names.insert(1,"chenzhonghua")#固定位置插入

names.insert(3,"小黄人")#固定位置插入

names[1] = "黑猫警长"#修改

names.remove("小黄人")#删除1

del names[0]#删除2

names.pop()#删除3(默认删除最后一个，输入下标固定删除)

print(names)print(names.index("wangza"))#查找列表数据的索引（即数据所在位置）

print(names[names.index("wangza")])

names.append("wangza")#追加

print(names)print(names.count("wangza"))#检查数据重复性

names.reverse()#数据反转

print(names)

names.sort()#排序

print(names)

names.clear()#清空

print(names)

names2= [1,2,3,4]

names.extend(names2)#合并列表

print(names,names2)

name2= names.copy()#软拷贝（有局限性）

name2 = copy.copy(names)#软拷贝1

name3 = names[:]#软拷贝2

name4 = list(names)#软拷贝3

name3 = names#完全拷贝

print(names)print(name2)

names[2] = "王炸"

print(names)print(name2)print(name3)print(names[2][1])importcopy

name2= copy.deepcopy(names)#深拷贝

print(names)print(name2)

基础循环：

#判断年龄

age = 60

guess_age = int(input("guess_age:"))

if guess_age == age:

print("yes,you got it.")

elif guess_age > age:

print("think smaller...")

else:

print("think bigger!")

#增加次数判断 1)

count = 0

age = 60

while True:

print("count:",count)

guess_age = int(input("guess_age:"))

if guess_age == age and count < 4:

print("yes,you got it.")

break

elif guess_age > age and count < 4:

print("think smaller,And count < 4...")

elif guess_age < age and count < 4:

print("think bigger!And count < 4")

else:

print("Game over!")

break

count = count +1

#增加次数判断 2)

count = 0

age = 60

while count < 4:

guess_age = int(input("guess_age:"))

if guess_age == age:

print("yes,you got it.")

break

elif guess_age > age:

print("think smaller,And count < 4...")

else:

print("think bigger!")

count = count +1

else:

print("More times than...!")

#增加次数判断 3)

age = 60

for i in range(4):

guess_age = int(input("guess_age:"))

if guess_age == age:

print("yes,you got it.")

break

elif guess_age > age:

print("think smaller,And count < 4...")

else:

print("think bigger!")

else:

print("More times than...!")

遍历打印：

for i in range(10):

print("-------",i)

for j in range(10):

print(j)

if j >5:

break
