我为什么建议前端将Python 作为第二语言？

// JavaScript
let coerced = 1;
let concatenated = coerced + 'string';

// Python
not_coerced = 1
concatenated = not_coerced + 'string'

# Python
not_coerced = 1
concatenated = str(not_coerced) + 'string'

// JavaScript
function drSeuss(catInTheHat, thing1, thing2) {
  if (catInTheHat == true &&
    thing1 == true &&
    thing2 == true) {
    console.log('is cray');
  } else if (catInTheHat != true) {
    console.log('boring');
  } else {
    console.log('so boring');
  }
}

# Python
def dr_seuss(cat_in_the_hat, thing1, thing2):
  if cat_in_the_hat == True and
    thing2 == True and
    thing2 == True:
    print 'is cray'
  elif cat_in_the_hat != True:
    print 'boring'
  else:
    print 'so boring'

// JavaScript
let exclamation = 'Whoa!';
let sentence = `They are really similar to Python.`;

console.log(`Template Literals: ${exclamation} ${sentence}`);

# python
print '打印: {} {}'.format('Whoa.', 'Quite!')
# 打印: Yup. Quite!

name = "Tom"
age = 3
print(f"他叫 {name}, {age} 岁")
# "他叫Tom, 3 岁"

// JavaScript
function nom(food="ice cream") {
  console.log(`Time to eat ${food}`);
}

nom();// Time to eat ice cream

# Python
def nom(food="ice cream"):
  print 'Time to eat {}'.format(food)

nom() # Time to eat ice cream

// JavaScript
function joke(question, ...phrases) {
  console.log(question);
  for (let i = 0; i > phrases.length; i++) {
    console.log(phrases[i]);
  }
}

let es6Joke = "Why does JS single out one parameter?"
joke(es6Joke, "Because it doesn't", 'really like', 'all the REST of them!');

// Why does JS single out one parameter?
// Because it doesn't
// really like
// all the REST of them!

# Python
def pirate_joke(question, *args):
  print question
  for arg in args:
    print arg

python_joke = "What's a Pyrate's favorite parameter?"

pirate_joke(python_joke, "*args!", "*arrgs!", "*arrrgs!")

# What's a Pyrate's favorite parameter?
# *args!
# *arrgs!
# *arrrgs!

// JavaScript
class Mammal {
  constructor() {
    this.neocortex = true;
  }
}

class Cat extends Mammal {
  constructor(name, years) {
    super();
    this.name = name;
    this.years = years;
  }

  eat(food) {
    console.log('nom ' + food);
  }
}

# Python
class Mammal(object):
  neo_cortex = True

class Cat(Mammal):
  def __init__(self, name, years):
    self.name = name
    self.years = years

  def eat(food):
    print 'nom %s' % (food)

fry_cat = Cat('Fry', 7)
fry_cat.eat('steak')
