为什么在\n
之后没有print (message_2.capitalize())
时,输出会在结果上强制换行?
# Input example python script
# Apparently in python 3.6, inputs can take strings instead of only raw values back in v2.7
message_0 = "good morning!"
message_1 = "please enter something for my input() value:"
message_2 = "the number you entered is ... "
message_3 = "ok, now this time enter value for my raw_input() value:"
message_final1 = "program ended."
message_final2 = "thank you!"
print ("\n\n")
print (message_0.capitalize() + "\n")
input_num = input(message_1.capitalize())
print ("\n")
# This line is obsoleted in python 3.6. raw_input() is renamed to input() .
# raw_input_num = raw_input(message_3.capitalize())
# data conversion
print ("Converting input_num() variable to float...\n")
input_num = float(input_num)
print ("\n")
print (message_2.capitalize())
print (input_num)
print ("\n")
print (message_final1.capitalize() + " " + message_final2.capitalize())
输出如下:
Good morning!
Please enter something for my input() value:67.3
Converting input_num() variable to float...
The number you entered is ...
67.3
Program ended. Thank you!

print()
会添加换行符。所以这两个陈述:
print (message_2.capitalize())
print (input_num)
会在消息和号码之间加上换行符。
传入两个对象以打印到一个 print()
来电:
print(message_2.capitalize(), input_num)
或告诉print()
不要通过将end
参数设置为空字符串来添加换行符:
print(message_2.capitalize(), end='')
print(input_num)

我已经问过我的朋友了,而不是仅仅删除我的问题,我想通过分享答案为这个网站增加价值:
# , operator here removes an unexpected newline. the print statement has a built in newline. That's why!
print (message_2.capitalize(),(input_num),"\n")
# Alternative way to display the answer
print (message_2.capitalize() + " " + str(input_num))
所以关键是使用逗号操作数或在答案上做一个字符串运算符。
