python-使用raw_input列出字典

Question

I'm using the following line to make a question with options from a dictionary

int(raw_input("Please select one of the following options %s: " % str(dict_options).strip('{}')))

This is the output, for example:

Please select one of the following options: 1: 'Development', 2: 'Certification', 3: 'Production'

This is the output I need:

Please select one of the following options:
1) Development
2) Certification
3) Production

There anyway to change the raw_input line? For some reason PyCharm need to put a text on the raw_input() function.

Answer 1

You can replace the commas with newline characters by doing .replace(',', '\\n') . The code looks something like:

dict_options = {1: 'Development', 2: 'Certification', 3: 'Production'}
print " " + str(dict_options).strip('{}').replace(',', '\n')

OUTPUT

 1: 'Development'
 2: 'Certification'
 3: 'Production'

The first space' purpose is to align the options.

If you want to replace the colon with a ) you can add an additional replace: .replace(':', ')')

If you want to get rid of the quotes you can do an additional: .replace("'", '')

etc.

Example

dict_options = {1: 'Development', 2: 'Certification', 3: 'Production'}

print " " + str(dict_options).strip('{}') \
                    .replace(',', '\n') \
                    .replace(':', ')') \
                    .replace("'", '')

OUTPUT

 1) Development
 2) Certification
 3) Production
