python - Automatically convert string to the right numerical type -

-

i wondering if there's elegant , easy way convert string (that know can converted number) corresponding numerical type. example, if string represents integer, want value converted int; same long, float, , on.

you use ast.literal_eval.

import ast  examples = ["1", "1.5", "999999999999999999999999999999999999999999", "23+42j"] item in examples:     result = ast.literal_eval(item)     print result     print type(result)

result:

1 <type 'int'> 1.5 <type 'float'> 999999999999999999999999999999999999999999 <type 'long'> (23+42j) <type 'complex'>

does know of elegant way combine 2 associative arrays in bash normal array? here's i'm talking about: in bash can combine 2 normal arrays follows: declare -ar array1=( 5 10 15 ) declare -ar array2=( 20 25 30 ) declare -ar array_both=( ${array1[@]} ${array2[@]} ) item in ${array_both[@]}; echo "item: ${item}" done i want same thing 2 associative arrays, following code not work: declare -ar array1=( [5]=true [10]=true [15]=true ) declare -ar array2=( [20]=true [25]=true [30]=true ) declare -ar array_both=( ${array1[@]} ${array2[@]} ) key in ${!array_both[@]}; echo "array_both[${key}]=${array_both[${key}]}" done it gives following error: ./associative_arrays.sh: line 3: array_both: true: must use subscript when assigning associative array the following work-around came with: declare -ar array1=( [5]=true [10]=true [15]=true ) declare -ar array2=( [20]=true [25]=true [30]=true ) declare -a array_both=() key in ${!array1[@]}; ...
