Question

Python

The following program contains a number of minor typos. Write the correct code and
comments about what was wrong. The type function returns the type for the value specified
as a parameter.

lex = {}

lex{’a’} = ’hej’

lex[’b’] = [5 9]

for k in lex.keys:

print(’Information for key {k}’)

print f’Val: {lex[k]}, Type: {type(lex[k])}’

Answer 1

lex = {}

#incorrect syntax

lex['a'] = 'hej'

#comma should be present in between 5 and 9 because they're list

lex['b'] = [5, 9]

#use keys() builtin method

for k in lex.keys():

#indentation should be followed

  print('Information for key {k}')

#syntax error: print should be print() parentheses missed  

  print (f'Val: {lex[k]}, Type: {type(lex[k])}')
