Range Over Built in Assembly Language
Based on the provided information, here’s the translated code and explanation in Python:
Here we use range
to sum the numbers in a list. Arrays work like this too.
nums = [2, 3, 4]
sum = 0
for num in nums:
sum += num
print("sum:", sum)
range
on arrays and lists provides both the index and value for each entry. Above we didn’t need the index, so we ignored it with the blank identifier _
. Sometimes we actually want the indexes though.
nums = [2, 3, 4]
for i, num in enumerate(nums):
if num == 3:
print("index:", i)
range
on dictionaries iterates over key/value pairs.
kvs = {"a": "apple", "b": "banana"}
for k, v in kvs.items():
print(f"{k} -> {v}")
range
can also iterate over just the keys of a dictionary.
for k in kvs:
print("key:", k)
range
on strings iterates over Unicode code points. The first value is the starting byte index of the character and the second the character itself.
for i, c in enumerate("go"):
print(i, ord(c))
To run the program, put the code in a .py
file and use python
to run it.
$ python range_over_built_in_types.py
sum: 9
index: 1
a -> apple
b -> banana
key: a
key: b
0 103
