I'm running Python version 2.7:
Python 2.7.12 (default, Dec 4 2017, 14:50:18)
[GCC 5.4.0 20160609] on linux2
When I try to run this line of code :
x = input('Enter your name:')
print('Hello, ' + x)
I have the following error:
$ python index.py
Enter your name:acb
Traceback (most recent call last):
File "index.py", line 1, in <module>
x = input('Enter your name:')
File "<string>", line 1, in <module>
NameError: name 'acb' is not defined
Does anyone know how to solve this?
The problem is that you are using the input function in Python 2.7 without apparently knowing how it works.
In this release, the input function will evaluate the input as a Python code. If you type "Generic" and there is no Generic object in context, it will give the name error, as in your example.
See this example:
a = 5
b = 6
c = 7
nome = input('Seu nome (digite a, b ou c): ')
print('Seja bem-vindo, ', nome)
See working at Repl.it
If you enter the values a , b or c into input , the result will be something like Seja bem-vindo, 5 , since it will evaluate the a entry for the object of the same name. / p>
So if you need to stay in version 2.7 of Python, use the raw_input function, or, if possible, migrate to a newer version of Python - the most current one at the moment is 3.7.
