# Example numbers
a = 11
b = 14
l = [a, b]

# Find the least least in the list
print(min(l))
11

# Subtract two numbers
print(b - a)
3

# Add 3 to a
print(a + 3)
14

# Import date
from datetime import date

# Create our dates
d1 = date(2017, 11, 5)
d2 = date(2017, 12, 4)
l = [d1, d2]

print(min(l))
2017-11-05

# Subtract two dates
delta = d2 - d1

print(delta.days)
29

# Import timedelta
from datetime import timedelta

# Create a 29 day timedelta
td = timedelta(days=29)
print(d1 + td)
2017-12-04

用 += 递增变量

# Initialize x to be zero
x = 0

# Increment x
x = x + 1

print(x)
1

# Initialize x to be zero
x = 0

# Increment x
x += 1

print(x)
1
