Input

if the input function is called, the program sequence is stopped until the user makes an entry. so that the user also knows what he must enter you can use "input prompt" this is optional a string is always the output

text = input("your input? ")
    # your input? 12
text
    # '12'

text = input("your input? ")
    # your input? [3, 6, 9]
text
    # '[3, 6, 9]'
type(text)
    # <class 'str'>

int & float​

if you now want to set a specific datatype you have to use int/float

text = int(input("your input? (float) "))
    # your input? (float) 42
text
    # 42
type(text)
    # <class 'int'>


text = float(input("your input? (float) "))
    # your input? (float) 3.69
text
    # 3.69
type(text)
    # <class 'float'>

Eval​

for lists, dictionaries and tuples eval is used

color = eval(input("Colors? "))
    # Colors? ["red","green","yellow"]
color, type(color)
    # (['red', 'green', 'yellow'], <class 'list'>)


frequency = eval(input("frequency? "))
    # frequency? {"a":5, "b":7, "c":3}
frequency, type(frequency)
    # ({'a': 5, 'b': 7, 'c': 3}, <class 'dict'>)
