python字符串跟整型互转

print ("整型：",int(50))
a=int(50)
print("整型:",a)
numStr = "50";
print ("字符串：",type(numStr))
convertedInt = int(numStr);
print("字符串转换为整型：",convertedInt)
convertedstr=str(a)
print("整型转换为字符串:",convertedInt)

输出结果：

C:\Python3.5\python.exe D:/15期/day04/day04daima/7.py
整型： 50
整型: 50
字符串： <class 'str'>
字符串转换为整型： 50
