I have a question. How can I make python script like:
i1 -> hello
i2 -> hi
i3 -> hurra
for (i = 1; i <= 3; i++)
print(text)
My desired output:
hello
hi
hurra
So I would like to iterate "links" in function but I want actual "linked values/strings" to iterate in "output". Maybe arrays can be used? Hope I'm clear.
Thanks!
Python doesn't have arrays like in C++ or Java. Instead you can use a list.
my_list = ['hello','hi','hurra']
for text in my_list:
print(text)
There are multiple ways to iterate the list, e.g.:
for i, text in enumerate(my_list):
print(i, text)
for i in range(0, len(my_list)):
print(my_list[i])
You could use it like "arrays", but there are many build-in functions that you would find very useful. This is a basic and essential data structure in Python. Most of books or tutorials would cover this topic in the first few chapters.
P.S.: The codes are for Python 3.
list is the actual counterpart to "arrays" of C++ or Java. And technically, Python does not have an array data type, but it has an array module.
You can use dictionaries for this purpose.
mydict={'i1':'hello','i2':'hi','i3':'hurra'}
for i, (key, value) in enumerate(mydict.items()):
print("index: {}, key: {}, value: {}".format(i, key, value))
x = ['hello', 'hi', 'hurra']
for item in x:
print(x)
#> hello
#> hi
#> hurra
