1. range
range() can produce a series of values
Syntax: range(start subscript (inclusive), end subscript ( Excluding)[, step size])
Example:
for value in range(1,5):
print(value)
print("*"*30)
for value in range(1,5,2):
print(value)Result:
1 2 3 4 ****************************** 1 3
2. Use list() to convert the values generated by range into a list
Example:
nums=list(range(1,5))
print(nums)
print("*"*30)
nums=list(range(1,5,2))
print(nums)Result:
[1, 2, 3, 4] ****************************** [1, 3]
3. List parsing: quickly generate a list of values
Syntax example: list=[value**2 for value in range (1,11)]
Example:
list=[value**2 for value in range(1,5)] print(list)
Result:
[1, 4, 9, 16]
